1 Version 3, 29 June 2007

4 Everyone is permitted to copy and distribute verbatim copies
5 of this license document, but changing it is not allowed.
6
7 Preamble
8
9 The GNU General Public License is a free, copyleft license for
10 software and other kinds of works.
11
12 The licenses for most software and other practical works are designed
13 to take away your freedom to share and change the works. By contrast,
14 the GNU General Public License is intended to guarantee your freedom to
15 share and change all versions of a program--to make sure it remains free
16 software for all its users. We, the Free Software Foundation, use the
17 GNU General Public License for most of our software; it applies also to
18 any other work released this way by its authors. You can apply it to
19 your programs, too.
20
21 When we speak of free software, we are referring to freedom, not
22 price. Our General Public Licenses are designed to make sure that you
23 have the freedom to distribute copies of free software (and charge for
24 them if you wish), that you receive source code or can get it if you
25 want it, that you can change the software or use pieces of it in new
26 free programs, and that you know you can do these things.
27
28 To protect your rights, we need to prevent others from denying you
29 these rights or asking you to surrender the rights. Therefore, you have
30 certain responsibilities if you distribute copies of the software, or if
31 you modify it: responsibilities to respect the freedom of others.
32
33 For example, if you distribute copies of such a program, whether
34 gratis or for a fee, you must pass on to the recipients the same
35 freedoms that you received. You must make sure that they, too, receive
36 or can get the source code. And you must show them these terms so they
37 know their rights.
38
39 Developers that use the GNU GPL protect your rights with two steps:
40 (1) assert copyright on the software, and (2) offer you this License
41 giving you legal permission to copy, distribute and/or modify it.
42
43 For the developers' and authors' protection, the GPL clearly explains
44 that there is no warranty for this free software. For both users' and
45 authors' sake, the GPL requires that modified versions be marked as
46 changed, so that their problems will not be attributed erroneously to
47 authors of previous versions.
48
49 Some devices are designed to deny users access to install or run
50 modified versions of the software inside them, although the manufacturer
51 can do so. This is fundamentally incompatible with the aim of
52 protecting users' freedom to change the software. The systematic
53 pattern of such abuse occurs in the area of products for individuals to
54 use, which is precisely where it is most unacceptable. Therefore, we
55 have designed this version of the GPL to prohibit the practice for those
56 products. If such problems arise substantially in other domains, we
57 stand ready to extend this provision to those domains in future versions
58 of the GPL, as needed to protect the freedom of users.
59
60 Finally, every program is threatened constantly by software patents.
61 States should not allow patents to restrict development and use of
62 software on general-purpose computers, but in those that do, we wish to
63 avoid the special danger that patents applied to a free program could
64 make it effectively proprietary. To prevent this, the GPL assures that
65 patents cannot be used to render the program non-free.
66
67 The precise terms and conditions for copying, distribution and
68 modification follow.
69
70 TERMS AND CONDITIONS
71
72 0. Definitions.
73
74 "This License" refers to version 3 of the GNU General Public License.
75
76 "Copyright" also means copyright-like laws that apply to other kinds of
77 works, such as semiconductor masks.
78
79 "The Program" refers to any copyrightable work licensed under this
80 License. Each licensee is addressed as "you". "Licensees" and
81 "recipients" may be individuals or organizations.
82
83 To "modify" a work means to copy from or adapt all or part of the work
84 in a fashion requiring copyright permission, other than the making of an
85 exact copy. The resulting work is called a "modified version" of the
86 earlier work or a work "based on" the earlier work.
87
88 A "covered work" means either the unmodified Program or a work based
89 on the Program.
90
91 To "propagate" a work means to do anything with it that, without
92 permission, would make you directly or secondarily liable for
93 infringement under applicable copyright law, except executing it on a
94 computer or modifying a private copy. Propagation includes copying,
95 distribution (with or without modification), making available to the
96 public, and in some countries other activities as well.
97
98 To "convey" a work means any kind of propagation that enables other
99 parties to make or receive copies. Mere interaction with a user through
100 a computer network, with no transfer of a copy, is not conveying.
101
102 An interactive user interface displays "Appropriate Legal Notices"
103 to the extent that it includes a convenient and prominently visible
104 feature that (1) displays an appropriate copyright notice, and (2)
105 tells the user that there is no warranty for the work (except to the
106 extent that warranties are provided), that licensees may convey the
107 work under this License, and how to view a copy of this License. If
108 the interface presents a list of user commands or options, such as a
109 menu, a prominent item in the list meets this criterion.
110
111 1. Source Code.
112
113 The "source code" for a work means the preferred form of the work
114 for making modifications to it. "Object code" means any non-source
115 form of a work.
116
117 A "Standard Interface" means an interface that either is an official
118 standard defined by a recognized standards body, or, in the case of
119 interfaces specified for a particular programming language, one that
120 is widely used among developers working in that language.
121
122 The "System Libraries" of an executable work include anything, other
123 than the work as a whole, that (a) is included in the normal form of
124 packaging a Major Component, but which is not part of that Major
125 Component, and (b) serves only to enable use of the work with that
126 Major Component, or to implement a Standard Interface for which an
127 implementation is available to the public in source code form. A
128 "Major Component", in this context, means a major essential component
129 (kernel, window system, and so on) of the specific operating system
130 (if any) on which the executable work runs, or a compiler used to
131 produce the work, or an object code interpreter used to run it.
132
133 The "Corresponding Source" for a work in object code form means all
134 the source code needed to generate, install, and (for an executable
135 work) run the object code and to modify the work, including scripts to
136 control those activities. However, it does not include the work's
137 System Libraries, or general-purpose tools or generally available free
138 programs which are used unmodified in performing those activities but
139 which are not part of the work. For example, Corresponding Source
140 includes interface definition files associated with source files for
141 the work, and the source code for shared libraries and dynamically
142 linked subprograms that the work is specifically designed to require,
143 such as by intimate data communication or control flow between those
144 subprograms and other parts of the work.
145
146 The Corresponding Source need not include anything that users
147 can regenerate automatically from other parts of the Corresponding
148 Source.
149
150 The Corresponding Source for a work in source code form is that
151 same work.
152
153 2. Basic Permissions.
154
155 All rights granted under this License are granted for the term of
156 copyright on the Program, and are irrevocable provided the stated
157 conditions are met. This License explicitly affirms your unlimited
158 permission to run the unmodified Program. The output from running a
159 covered work is covered by this License only if the output, given its
160 content, constitutes a covered work. This License acknowledges your
161 rights of fair use or other equivalent, as provided by copyright law.
162
163 You may make, run and propagate covered works that you do not
164 convey, without conditions so long as your license otherwise remains
165 in force. You may convey covered works to others for the sole purpose
166 of having them make modifications exclusively for you, or provide you
167 with facilities for running those works, provided that you comply with
168 the terms of this License in conveying all material for which you do
169 not control copyright. Those thus making or running the covered works
170 for you must do so exclusively on your behalf, under your direction
171 and control, on terms that prohibit them from making any copies of
172 your copyrighted material outside their relationship with you.
173
174 Conveying under any other circumstances is permitted solely under
175 the conditions stated below. Sublicensing is not allowed; section 10
176 makes it unnecessary.
177
178 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
179
180 No covered work shall be deemed part of an effective technological
181 measure under any applicable law fulfilling obligations under article
182 11 of the WIPO copyright treaty adopted on 20 December 1996, or
183 similar laws prohibiting or restricting circumvention of such
184 measures.
185
186 When you convey a covered work, you waive any legal power to forbid
187 circumvention of technological measures to the extent such circumvention
188 is effected by exercising rights under this License with respect to
189 the covered work, and you disclaim any intention to limit operation or
190 modification of the work as a means of enforcing, against the work's
191 users, your or third parties' legal rights to forbid circumvention of
192 technological measures.
193
194 4. Conveying Verbatim Copies.
195
196 You may convey verbatim copies of the Program's source code as you
197 receive it, in any medium, provided that you conspicuously and
198 appropriately publish on each copy an appropriate copyright notice;
199 keep intact all notices stating that this License and any
200 non-permissive terms added in accord with section 7 apply to the code;
201 keep intact all notices of the absence of any warranty; and give all
202 recipients a copy of this License along with the Program.
203
204 You may charge any price or no price for each copy that you convey,
205 and you may offer support or warranty protection for a fee.
206
207 5. Conveying Modified Source Versions.
208
209 You may convey a work based on the Program, or the modifications to
210 produce it from the Program, in the form of source code under the
211 terms of section 4, provided that you also meet all of these conditions:
212
213 a) The work must carry prominent notices stating that you modified
214 it, and giving a relevant date.
215
216 b) The work must carry prominent notices stating that it is
217 released under this License and any conditions added under section
218 7. This requirement modifies the requirement in section 4 to
219 "keep intact all notices".
220
221 c) You must license the entire work, as a whole, under this
222 License to anyone who comes into possession of a copy. This
223 License will therefore apply, along with any applicable section 7
224 additional terms, to the whole of the work, and all its parts,
225 regardless of how they are packaged. This License gives no
226 permission to license the work in any other way, but it does not
227 invalidate such permission if you have separately received it.
228
229 d) If the work has interactive user interfaces, each must display
230 Appropriate Legal Notices; however, if the Program has interactive
231 interfaces that do not display Appropriate Legal Notices, your
232 work need not make them do so.
233
234 A compilation of a covered work with other separate and independent
235 works, which are not by their nature extensions of the covered work,
236 and which are not combined with it such as to form a larger program,
237 in or on a volume of a storage or distribution medium, is called an
238 "aggregate" if the compilation and its resulting copyright are not
239 used to limit the access or legal rights of the compilation's users
240 beyond what the individual works permit. Inclusion of a covered work
241 in an aggregate does not cause this License to apply to the other
242 parts of the aggregate.
243
244 6. Conveying Non-Source Forms.
245
246 You may convey a covered work in object code form under the terms
247 of sections 4 and 5, provided that you also convey the
248 machine-readable Corresponding Source under the terms of this License,
249 in one of these ways:
250
251 a) Convey the object code in, or embodied in, a physical product
252 (including a physical distribution medium), accompanied by the
253 Corresponding Source fixed on a durable physical medium
254 customarily used for software interchange.
255
256 b) Convey the object code in, or embodied in, a physical product
257 (including a physical distribution medium), accompanied by a
258 written offer, valid for at least three years and valid for as
259 long as you offer spare parts or customer support for that product
260 model, to give anyone who possesses the object code either (1) a
261 copy of the Corresponding Source for all the software in the
262 product that is covered by this License, on a durable physical
263 medium customarily used for software interchange, for a price no
264 more than your reasonable cost of physically performing this
265 conveying of source, or (2) access to copy the
266 Corresponding Source from a network server at no charge.
267
268 c) Convey individual copies of the object code with a copy of the
269 written offer to provide the Corresponding Source. This
270 alternative is allowed only occasionally and noncommercially, and
271 only if you received the object code with such an offer, in accord
272 with subsection 6b.
273
274 d) Convey the object code by offering access from a designated
275 place (gratis or for a charge), and offer equivalent access to the
276 Corresponding Source in the same way through the same place at no
277 further charge. You need not require recipients to copy the
278 Corresponding Source along with the object code. If the place to
279 copy the object code is a network server, the Corresponding Source
280 may be on a different server (operated by you or a third party)
281 that supports equivalent copying facilities, provided you maintain
282 clear directions next to the object code saying where to find the
283 Corresponding Source. Regardless of what server hosts the
284 Corresponding Source, you remain obligated to ensure that it is
285 available for as long as needed to satisfy these requirements.
286
287 e) Convey the object code using peer-to-peer transmission, provided
288 you inform other peers where the object code and Corresponding
289 Source of the work are being offered to the general public at no
290 charge under subsection 6d.
291
292 A separable portion of the object code, whose source code is excluded
293 from the Corresponding Source as a System Library, need not be
294 included in conveying the object code work.
295
296 A "User Product" is either (1) a "consumer product", which means any
297 tangible personal property which is normally used for personal, family,
298 or household purposes, or (2) anything designed or sold for incorporation
299 into a dwelling. In determining whether a product is a consumer product,
300 doubtful cases shall be resolved in favor of coverage. For a particular
301 product received by a particular user, "normally used" refers to a
302 typical or common use of that class of product, regardless of the status
303 of the particular user or of the way in which the particular user
304 actually uses, or expects or is expected to use, the product. A product
305 is a consumer product regardless of whether the product has substantial
306 commercial, industrial or non-consumer uses, unless such uses represent
307 the only significant mode of use of the product.
308
309 "Installation Information" for a User Product means any methods,
310 procedures, authorization keys, or other information required to install
311 and execute modified versions of a covered work in that User Product from
312 a modified version of its Corresponding Source. The information must
313 suffice to ensure that the continued functioning of the modified object
314 code is in no case prevented or interfered with solely because
315 modification has been made.
316
317 If you convey an object code work under this section in, or with, or
318 specifically for use in, a User Product, and the conveying occurs as
319 part of a transaction in which the right of possession and use of the
320 User Product is transferred to the recipient in perpetuity or for a
321 fixed term (regardless of how the transaction is characterized), the
322 Corresponding Source conveyed under this section must be accompanied
323 by the Installation Information. But this requirement does not apply
324 if neither you nor any third party retains the ability to install
325 modified object code on the User Product (for example, the work has
326 been installed in ROM).
327
328 The requirement to provide Installation Information does not include a
329 requirement to continue to provide support service, warranty, or updates
330 for a work that has been modified or installed by the recipient, or for
331 the User Product in which it has been modified or installed. Access to a
332 network may be denied when the modification itself materially and
333 adversely affects the operation of the network or violates the rules and
334 protocols for communication across the network.
335
336 Corresponding Source conveyed, and Installation Information provided,
337 in accord with this section must be in a format that is publicly
338 documented (and with an implementation available to the public in
339 source code form), and must require no special password or key for
340 unpacking, reading or copying.
341
342 7. Additional Terms.
343
344 "Additional permissions" are terms that supplement the terms of this
345 License by making exceptions from one or more of its conditions.
346 Additional permissions that are applicable to the entire Program shall
347 be treated as though they were included in this License, to the extent
348 that they are valid under applicable law. If additional permissions
349 apply only to part of the Program, that part may be used separately
350 under those permissions, but the entire Program remains governed by
351 this License without regard to the additional permissions.
352
353 When you convey a copy of a covered work, you may at your option
354 remove any additional permissions from that copy, or from any part of
355 it. (Additional permissions may be written to require their own
356 removal in certain cases when you modify the work.) You may place
357 additional permissions on material, added by you to a covered work,
358 for which you have or can give appropriate copyright permission.
359
360 Notwithstanding any other provision of this License, for material you
361 add to a covered work, you may (if authorized by the copyright holders of
362 that material) supplement the terms of this License with terms:
363
364 a) Disclaiming warranty or limiting liability differently from the
365 terms of sections 15 and 16 of this License; or
366
367 b) Requiring preservation of specified reasonable legal notices or
368 author attributions in that material or in the Appropriate Legal
369 Notices displayed by works containing it; or
370
371 c) Prohibiting misrepresentation of the origin of that material, or
372 requiring that modified versions of such material be marked in
373 reasonable ways as different from the original version; or
374
375 d) Limiting the use for publicity purposes of names of licensors or
376 authors of the material; or
377
378 e) Declining to grant rights under trademark law for use of some
379 trade names, trademarks, or service marks; or
380
381 f) Requiring indemnification of licensors and authors of that
382 material by anyone who conveys the material (or modified versions of
383 it) with contractual assumptions of liability to the recipient, for
384 any liability that these contractual assumptions directly impose on
385 those licensors and authors.
386
387 All other non-permissive additional terms are considered "further
388 restrictions" within the meaning of section 10. If the Program as you
389 received it, or any part of it, contains a notice stating that it is
390 governed by this License along with a term that is a further
391 restriction, you may remove that term. If a license document contains
392 a further restriction but permits relicensing or conveying under this
393 License, you may add to a covered work material governed by the terms
394 of that license document, provided that the further restriction does
395 not survive such relicensing or conveying.
396
397 If you add terms to a covered work in accord with this section, you
398 must place, in the relevant source files, a statement of the
399 additional terms that apply to those files, or a notice indicating
400 where to find the applicable terms.
401
402 Additional terms, permissive or non-permissive, may be stated in the
403 form of a separately written license, or stated as exceptions;
404 the above requirements apply either way.
405
406 8. Termination.
407
408 You may not propagate or modify a covered work except as expressly
409 provided under this License. Any attempt otherwise to propagate or
410 modify it is void, and will automatically terminate your rights under
411 this License (including any patent licenses granted under the third
412 paragraph of section 11).
413
414 However, if you cease all violation of this License, then your
415 license from a particular copyright holder is reinstated (a)
416 provisionally, unless and until the copyright holder explicitly and
417 finally terminates your license, and (b) permanently, if the copyright
418 holder fails to notify you of the violation by some reasonable means
419 prior to 60 days after the cessation.
420
421 Moreover, your license from a particular copyright holder is
422 reinstated permanently if the copyright holder notifies you of the
423 violation by some reasonable means, this is the first time you have
424 received notice of violation of this License (for any work) from that
425 copyright holder, and you cure the violation prior to 30 days after
426 your receipt of the notice.
427
428 Termination of your rights under this section does not terminate the
429 licenses of parties who have received copies or rights from you under
430 this License. If your rights have been terminated and not permanently
431 reinstated, you do not qualify to receive new licenses for the same
432 material under section 10.
433
434 9. Acceptance Not Required for Having Copies.
435
436 You are not required to accept this License in order to receive or
437 run a copy of the Program. Ancillary propagation of a covered work
438 occurring solely as a consequence of using peer-to-peer transmission
439 to receive a copy likewise does not require acceptance. However,
440 nothing other than this License grants you permission to propagate or
441 modify any covered work. These actions infringe copyright if you do
442 not accept this License. Therefore, by modifying or propagating a
443 covered work, you indicate your acceptance of this License to do so.
444
445 10. Automatic Licensing of Downstream Recipients.
446
447 Each time you convey a covered work, the recipient automatically
448 receives a license from the original licensors, to run, modify and
449 propagate that work, subject to this License. You are not responsible
450 for enforcing compliance by third parties with this License.
451
452 An "entity transaction" is a transaction transferring control of an
453 organization, or substantially all assets of one, or subdividing an
454 organization, or merging organizations. If propagation of a covered
455 work results from an entity transaction, each party to that
456 transaction who receives a copy of the work also receives whatever
457 licenses to the work the party's predecessor in interest had or could
458 give under the previous paragraph, plus a right to possession of the
459 Corresponding Source of the work from the predecessor in interest, if
460 the predecessor has it or can get it with reasonable efforts.
461
462 You may not impose any further restrictions on the exercise of the
463 rights granted or affirmed under this License. For example, you may
464 not impose a license fee, royalty, or other charge for exercise of
465 rights granted under this License, and you may not initiate litigation
466 (including a cross-claim or counterclaim in a lawsuit) alleging that
467 any patent claim is infringed by making, using, selling, offering for
468 sale, or importing the Program or any portion of it.
469
470 11. Patents.
471
472 A "contributor" is a copyright holder who authorizes use under this
473 License of the Program or a work on which the Program is based. The
474 work thus licensed is called the contributor's "contributor version".
475
476 A contributor's "essential patent claims" are all patent claims
477 owned or controlled by the contributor, whether already acquired or
478 hereafter acquired, that would be infringed by some manner, permitted
479 by this License, of making, using, or selling its contributor version,
480 but do not include claims that would be infringed only as a
481 consequence of further modification of the contributor version. For
482 purposes of this definition, "control" includes the right to grant
483 patent sublicenses in a manner consistent with the requirements of
484 this License.
485
486 Each contributor grants you a non-exclusive, worldwide, royalty-free
487 patent license under the contributor's essential patent claims, to
488 make, use, sell, offer for sale, import and otherwise run, modify and
489 propagate the contents of its contributor version.
490
491 In the following three paragraphs, a "patent license" is any express
492 agreement or commitment, however denominated, not to enforce a patent
493 (such as an express permission to practice a patent or covenant not to
494 sue for patent infringement). To "grant" such a patent license to a
495 party means to make such an agreement or commitment not to enforce a
496 patent against the party.
497
498 If you convey a covered work, knowingly relying on a patent license,
499 and the Corresponding Source of the work is not available for anyone
500 to copy, free of charge and under the terms of this License, through a
501 publicly available network server or other readily accessible means,
502 then you must either (1) cause the Corresponding Source to be so
503 available, or (2) arrange to deprive yourself of the benefit of the
504 patent license for this particular work, or (3) arrange, in a manner
505 consistent with the requirements of this License, to extend the patent
506 license to downstream recipients. "Knowingly relying" means you have
507 actual knowledge that, but for the patent license, your conveying the
508 covered work in a country, or your recipient's use of the covered work
509 in a country, would infringe one or more identifiable patents in that
510 country that you have reason to believe are valid.
511
512 If, pursuant to or in connection with a single transaction or
513 arrangement, you convey, or propagate by procuring conveyance of, a
514 covered work, and grant a patent license to some of the parties
515 receiving the covered work authorizing them to use, propagate, modify
516 or convey a specific copy of the covered work, then the patent license
517 you grant is automatically extended to all recipients of the covered
518 work and works based on it.
519
520 A patent license is "discriminatory" if it does not include within
521 the scope of its coverage, prohibits the exercise of, or is
522 conditioned on the non-exercise of one or more of the rights that are
523 specifically granted under this License. You may not convey a covered
524 work if you are a party to an arrangement with a third party that is
525 in the business of distributing software, under which you make payment
526 to the third party based on the extent of your activity of conveying
527 the work, and under which the third party grants, to any of the
528 parties who would receive the covered work from you, a discriminatory
529 patent license (a) in connection with copies of the covered work
530 conveyed by you (or copies made from those copies), or (b) primarily
531 for and in connection with specific products or compilations that
532 contain the covered work, unless you entered into that arrangement,
533 or that patent license was granted, prior to 28 March 2007.
534
535 Nothing in this License shall be construed as excluding or limiting
536 any implied license or other defenses to infringement that may
537 otherwise be available to you under applicable patent law.
538
539 12. No Surrender of Others' Freedom.
540
541 If conditions are imposed on you (whether by court order, agreement or
542 otherwise) that contradict the conditions of this License, they do not
543 excuse you from the conditions of this License. If you cannot convey a
544 covered work so as to satisfy simultaneously your obligations under this
545 License and any other pertinent obligations, then as a consequence you may
546 not convey it at all. For example, if you agree to terms that obligate you
547 to collect a royalty for further conveying from those to whom you convey
548 the Program, the only way you could satisfy both those terms and this
549 License would be to refrain entirely from conveying the Program.
550
551 13. Use with the GNU Affero General Public License.
552
553 Notwithstanding any other provision of this License, you have
554 permission to link or combine any covered work with a work licensed
555 under version 3 of the GNU Affero General Public License into a single
556 combined work, and to convey the resulting work. The terms of this
557 License will continue to apply to the part which is the covered work,
558 but the special requirements of the GNU Affero General Public License,
559 section 13, concerning interaction through a network will apply to the
560 combination as such.
561
562 14. Revised Versions of this License.
563
564 The Free Software Foundation may publish revised and/or new versions of
565 the GNU General Public License from time to time. Such new versions will
566 be similar in spirit to the present version, but may differ in detail to
567 address new problems or concerns.
568
569 Each version is given a distinguishing version number. If the
570 Program specifies that a certain numbered version of the GNU General
571 Public License "or any later version" applies to it, you have the
572 option of following the terms and conditions either of that numbered
573 version or of any later version published by the Free Software
574 Foundation. If the Program does not specify a version number of the
575 GNU General Public License, you may choose any version ever published
576 by the Free Software Foundation.
577
578 If the Program specifies that a proxy can decide which future
579 versions of the GNU General Public License can be used, that proxy's
580 public statement of acceptance of a version permanently authorizes you
581 to choose that version for the Program.
582
583 Later license versions may give you additional or different
584 permissions. However, no additional obligations are imposed on any
585 author or copyright holder as a result of your choosing to follow a
586 later version.
587
588 15. Disclaimer of Warranty.
589
590 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
591 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
592 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
593 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
594 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
595 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
596 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
597 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
598
599 16. Limitation of Liability.
600
601 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
602 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
603 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
604 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
605 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
606 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
607 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
608 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
609 SUCH DAMAGES.
610
611 17. Interpretation of Sections 15 and 16.
612
613 If the disclaimer of warranty and limitation of liability provided
614 above cannot be given local legal effect according to their terms,
615 reviewing courts shall apply local law that most closely approximates
616 an absolute waiver of all civil liability in connection with the
617 Program, unless a warranty or assumption of liability accompanies a
618 copy of the Program in return for a fee.
619
620 END OF TERMS AND CONDITIONS
621
622 How to Apply These Terms to Your New Programs
623
624 If you develop a new program, and you want it to be of the greatest
625 possible use to the public, the best way to achieve this is to make it
626 free software which everyone can redistribute and change under these terms.
627
628 To do so, attach the following notices to the program. It is safest
629 to attach them to the start of each source file to most effectively
630 state the exclusion of warranty; and each file should have at least
631 the "copyright" line and a pointer to where the full notice is found.
632
633 <one line to give the program's name and a brief idea of what it does.>
634 Copyright (C) <year> <name of author>
635
636 This program is free software: you can redistribute it and/or modify
637 it under the terms of the GNU General Public License as published by
638 the Free Software Foundation, either version 3 of the License, or
639 (at your option) any later version.
640
641 This program is distributed in the hope that it will be useful,
642 but WITHOUT ANY WARRANTY; without even the implied warranty of
643 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
644 GNU General Public License for more details.
645
646 You should have received a copy of the GNU General Public License
647 along with this program. If not, see <http://www.gnu.org/licenses/>.
648
649 Also add information on how to contact you by electronic and paper mail.
650
651 If the program does terminal interaction, make it output a short
652 notice like this when it starts in an interactive mode:
653
654 <program> Copyright (C) <year> <name of author>
655 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
656 This is free software, and you are welcome to redistribute it
657 under certain conditions; type `show c' for details.
658
659 The hypothetical commands `show w' and `show c' should show the appropriate
660 parts of the General Public License. Of course, your program's commands
661 might be different; for a GUI interface, you would use an "about box".
662
663 You should also get your employer (if you work as a programmer) or school,
664 if any, to sign a "copyright disclaimer" for the program, if necessary.
665 For more information on this, and how to apply and follow the GNU GPL, see
666 <http://www.gnu.org/licenses/>.
667
668 The GNU General Public License does not permit incorporating your program
669 into proprietary programs. If your program is a subroutine library, you
670 may consider it more useful to permit linking proprietary applications with
671 the library. If this is what you want to do, use the GNU Lesser General
672 Public License instead of this License. But first, please read
673 <http://www.gnu.org/philosophy/why-not-lgpl.html>.

4 Fix "odd" files created by frequent power-loss.
5
6 After running many power losses the filesystem can degrate, containing "odd"
7 files making the filesystem corrupt that could not be solved by fsck:
8
9 * file was not visible in a ls -l
10 * ls -i reported a "invalid file name" on the console
11 * a test program with diropen/dirread showed the file, a stat on this file
12 failed
13 * file was not accessible and could not be deleted
14
15 After digging into the code we found why fsck didn't repair the file system:
16 One thing was we don't have short filenames. Another issue was that the LFN
17 pointer was set to NULL and so it looked like we didn't have short and long
18 filenames.
19
20 Our patch of check.c includes:
21
22 * returns 1 from function bad_name() in case no short and no long filename
23 exist
24 * auto_rename() and rename_file() got a special handling for the case no short
25 file name exist:
26 - it enables the short file name (we think here was a weakness of the old
27 code: it changed the short filename but didn't enabled it in the
28 file->dir_ent.lcase entry)
29 - it reset all attributes except ATTR_DIR and ATTR_VOLUME
30
31 This solved our problem pretty well.

73 Prevent corruption of FAT during fsck on 64 bit platforms.
74
75 unsigned long is 64 bit on x86-64, which means set_fat was writing two
76 entries, which corrupts the next entry. This can cause loss of data in
77 another file.

93 Fixed dosfsck on big endian platforms (Resolves: rhbz#1029695).
94
95 It seems there is problem in the double conversion on big endians.
96 The first conversion is done by the explicit conversion to __u16
97 in the GET_UNALIGNED_W macro, so the secondary conversion by le16toh
98 seems to be redundant (and wrong).

121
122 Fixing "Fixing default sectors per cluster for FAT32" for UEFI.
123
124 FAT32 "EFI System Partition" is basically required for UEFI boot;
125 commit ge048a8d broke that for me with both virtualbox-4.2 and
126 real hardware (ASUS C60M1-I to be exact) given ~250Mb filesystem.
127
128 This commit amends that one by reverting its effects for these
129 small sizes by restoring 512b cluster size for <= 260Mb FAT32.

293 Don't align FAT32 reserved sectors to cluster size.
294
295 For certain file system sizes (in particular, exact GB sizes -
296 don't ask me why) a Technisat HD S2 Plus DVB receiver will still
297 choke on mkdosfs generated file systems, even if the sectors per
298 cluster problem is fixed.
299
300 By comparing the properties of generated FAT32 FS with results
301 of the Windows tool "h2format" (www.heise.de/download/h2format.html),
302 I found that the remaining problems were caused by rounding of the
303 reserved sectors and FAT space to cluster size (the h2format tool
304 doesn't do this).

467 Date: Mon Apr 22 12:29:51 2013 +0100
468
469 Allow operation on SH4 CPUs and remove compiler warnings.
470
471 Simplify the GET_UNALIGNED_W macro and use it in all cases instead of making it
472 conditional on CPU types. This missed some CPUs that needed it (e.g. SH4), and
473 in any case the implementation caused "dereferencing type-punned pointer will
474 break strict-aliasing rules" warnings.
475
476 Enable extra warnings, but disable signed comparison and missing field
477 initializer warnings as these are not helpful.
478
479 Update write_boot_label() so that the boot_sector_16 and boot_sector cases are
480 handled separately instead of using an aliased pointer, as that causes
481 "dereferencing type-punned pointer will break strict-aliasing rules" warnings.
482
483 Make date_dos2unix(), usage() and cdiv() static functions as they are only used
484 in the files in which they are declared.
485
486 Update bad_name() and lfn_get() so that the extension is processed separately
487 instead of by indexing past the end of the name field as that causes "array
488 subscript is above array bounds" warnings.
489
490 Update the dosfsck() main function to avoid a warning that free_clusters may
491 be used uninitialized. Do not print the final count of files and clusters when
492 dosfsck is run with the "-b" option because the used files and clusters have
493 not been counted in this case.
494
495 Alter the setup_tables() function so that it does not cause an "array subscript
496 is below array bounds" warning.

764
765 Correcting miscalculation of sector number in some cases.
766
767 mkdosfs will incorrectly calculate the number of sectors of a
768 given FAT partition if the number sectors are odd due to
769 count_blocks incorrectly handling the remainder of a division
770 operation. This miscalculation causes the OMAP4 bootloader to
771 fail to boot.
772
773 This bug can be observed by comparing the total sector size in
774 fdisk expert more to fsck.msdos; this discrepancy only shows up
775 when the number of sectors are odd.

809 The problem is that alloc_rootdir_entry counts with 10000 files at max, but the
810 filename buffer is only 8 chars long. Due to pattern mask used it results to
811 only 10 files at max (FSCK0-9REC). If there is more than 10 files, it overflows

852 Add better error message when the device cannot be opened.
853
854 This is helpful for SD cards or other removable media which have an enabled
855 write lock -- without the "Permission denied" message, the user has to strace
856 mkdosfs to find out what's going on.

973
974 When compiling a 32-bit version of dosfstools on an x86_64 machine,
975 the resulting applications report strange errors on "large" (> 2 GiB)
976 partitions:
977
978 Seek to -2118967808:Invalid argument
979
980 Warning: Filesystem is FAT32 according to fat_length and fat32_length fields,
981 but has only 8613 clusters, less than the required minimum of 65525.
982 This may lead to problems on some systems.
983
984 This appears to be due to compilation with a 32-bit off_t and lseek() library
985 function.
986
987 Use lseek64 for positioning, and change some suspect uses of off_t to loff_t.

1013 mkdosfs: correct alignment of the root directory.
1014
1015 Correct the code to align the root directory; it was broken before
1016 since bs.dir_entries had already been set at the point of alignment.
1017 This patch removes the dual use of bs.dir_entries and root_dir_entries
1018 to carry the same information: the information is carried in
1019 root_dir_entires exclusively, and then bs.dir_entries is set inside
1020 setup_tables() at a late point.
1021
1022 The code to align the root directory is also wrapped in
1023 if (align_structures); this avoids rounding the number of root
1024 directory entries up to a whole sector when used with -a
1025 (i.e. preserves the previous behavior.)

1052 mkdosfs: by default align all structures to cluster boundaries
1053
1054 Align all data structures (reserved sectors, FATs, root directory for
1055 FAT12/16) to an even multiple of the cluster size. This means that if
1056 the partition is aligned, so will all clusters be. This adds
1057 significant performance for anything where the physical sector size is
1058 larger than the logical sector size, e.g. flash media or large-sector
1059 hard disks.

1298 * FAT16 filesystems with 65525 clusters or more will be rejected
1299 (Before, this was not tested for. Up to 65535 clusters were accepted
1300 as good).

1302 * For FAT32 filesystems with less than 65525 a warning message will be
1303 output.
1304
1305 Macro MSDOS_FAT12 is now replaced by FAT12_THRESHOLD to make it

0 Announcing the release of mkdosfs version 0.3b (Yggdrasil)
1
2 It seems I didn't get the bug completely fixed in 0.3a. Some
3 borderline cases would still allocate too many sectors for the FAT.
4 Again, nothing to worry about, just a nitpick -- this one would only
5 in certain cases add one sector per FAT.
6
7 Announcing the release of mkdosfs version 0.3a (Yggdrasil)
8
9 Fixed a bug which would cause too many sectors to be reserved for the
10 FAT (filesystem will still work fine, but have slightly less space
11 available).
12
13 Announcing the release of mkdosfs version 0.3 (Yggdrasil)
14
15 This version correctly handles even very large filesystems, and
16 properly supports the modern (3.3+) DOS bootsector format, including a
17 message printed on boot attempts.

25 Announcing the release of mkdosfs version 0.2
26
27
28 I've just uploaded mkdosfs to sunsite.unc.edu. It works in a similar way
29 to Remy Card's mke2fs, but creates an MS-DOS filesystem.
30
31 The filename is mkdosfs-0.2.tar.gz.
32
33 This second release should fix a small bug that could lead to FAT sizes that
34 Linux's dosfs would accept but MS-DOS wouldn't.
35
36 The archive contains a manual page, binary and source versions.

36 - mkdosfs: better error message if called without parameters (also
37 suggested by Michal)
38
39 version 2.9
40 ===========
41
42 - dosfsck: if EOF from stdin, exit with error code
43 - dosfsck: Fix potential for "Internal error: next_cluster on bad cluster".
44 - dosfsck: When clearing long file names, don't overwrite the dir
45 entries with all zeros, but put 0xe5 into the first byte.
46 Otherwise, some OSes stop reading the directory at that point...
47 - dosfsck: in statistics printed by -v, fix 32bit overflow in number
48 of data bytes.
49 - dosfsck: fix an potential overflow in "too many clusters" check
50 - dosfsck: fix 64bit problem in fat.c (Debian bug #152769)
51 - dosfsck: allow FAT size > 32MB.
52 - dosfsck: allow for only one FAT
53 - dosfsck: with -v, also check that last sector of the filesystem can
54 be read (in case a partition is smaller than the fs thinks)
55 - mkdosfs: add note in manpage that creating bootable filesystems is
56 not supported.
57 - mkdosfs: better error message with pointer to -I if target is a
58 full-disk device.
59
60 version 2.8
61 ===========
62
63 - dosfsck: Fixed endless loop whenever a volume label was present.
64
65 version 2.7
66 ===========
67
68 - dosfsck: Don't check volume label for bad characters, everything
69 seems to be allowed there... Also ignore duplicate names where one of
70 them is a volume label.
71
72 version 2.6
73 ===========
74
75 - mkdosfs: Added correct heads definition for 2.88M floppies if not
76 created via loopback.
77 - dosfsck: If boot sector and its backup are different (FAT32), offer
78 to write the backup to sector 0. (tnx to Pavel Roskin for this)
79 - For 64 bit alpha, struct bootsector in dosfsck.h must be defined
80 with __attribute__((packed)).
81 - mkdosfs now actually accepts -R option. (tnx to David Kerrawn)
82 - Fixed typo in dosfsck boot.c (recognition of boot signature in FSINFO)
83 - Various compilation fixes for 2.4 kernel headers and for ia64.
84
85 version 2.5
86 ===========
87
88 - The llseek() implementation for alpha didn't really work; fixed it.
89
90 version 2.4
91 ===========
92
93 - Fix compiling problem on alpha (made a silly typo...)
94
95 version 2.3
96 ===========
97
98 - mkdosfs: Fixed usage message (printed only "bad address").
99 - both: made man pages and usage statements more consistent.
100 - both: fix llseek function for alpha.
101 - dosfsck: fix reading of unaligned fields in boot sector for alpha.
102 - dosfsck: fixed renaming of files (extension wasn't really written).
103
104 version 2.2
105 ===========
106
107 - Added dosfsck/COPYING, putting dosfsck officially under GPL (Werner
108 and I agree that it should be GPL).
109 - mkdosfs: Allow creation of a 16 bit FAT on filesystems that are too
110 small for it if the user explicitly selected FAT16 (but a warning
111 is printed). Formerly, you got the misleading error message "make
112 the fs a bit smaller".
113 - dosfsck: new option -y as synonym for -y; for compability with
114 other fs checkers, which also accept this option.
115 - dosfsck: Now prints messages similar to e2fsck: at start version
116 and feature list; at end number of files (and directories) and
117 number of used/total clusters. This makes the printouts of *fsck at
118 boot time nicer.
119 - dosfsck: -a (auto repair) now turns on -f (salvage files), too. -a
120 should act as non-destructive as possible, so lost clusters should
121 be assigned to files. Otherwise the data in them might be
122 overwritten later.
123 - dosfsck: Don't drop a directory with lots of bad entries in
124 auto-repair mode for the same reason as above.
125 - dosfsck: avoid deleting the whole FAT32 root dir if something is
126 wrong with it (bad start cluster or the like).
127 - general: also create symlinks {mkfs,fsck}.vfat.8 to the respective
128 real man pages.
129
130 version 2.1
131 ===========
132
133 - Fix some forgotten loff_t's for filesystems > 4GB. (Thanks to
134 <ki@kretz.co.at>).
135 - Fix typo in mkdosfs manpage.
136 - Removed inclusion of <linux/loop.h> from mkdosfs.c; it's unnecessary and
137 caused problems in some environments.
138 - Fix condition when to expect . and .. entries in a directory. (Was
139 wrong for non-FAT32 if first entry in root dir was a directory also.)
140 - Also create mkfs.vfat and fsck.vfat symlinks, so that also
141 filesystems listed with type "vfat" in /etc/fstab can be
142 automatically checked.
143
144 version 2.0
145 ===========
146
147 - merge of mkdosfs and dosfstools in one package
148 - new maintainer: Roman Hodek <Roman.Hodek@informatik.uni-erlangen.de>
149 - FAT32 support in both mkdosfs and dosfsck
150 - VFAT (long filename) support in dosfsck
151 - Support for Atari variant of MS-DOS filesystem in both tools
152 - Working support for big-endian systems in both tools
153 - Better support for loop devices in mkdosfs: usual floppy sizes are
154 detected and media byte etc. set accordingly; if loop fs has no
155 standard floppy size, use hd params
156 (mainly by Giuliano Procida <gpp10@cus.cam.ac.uk>)
157 - Removed lots of gcc warnings
158 - Fixed some minor calculation bugs in mkdosfs.

2 Better algorithm to select cluster sizes on large filesystems.
3 Added bogus boot sector code that on attempts to boot prints a
4 message (which can be chosen at mkdosfs time) and lets the user
5 press any key and try again. Corrected support for 1.2 Mb
6 floppies. mkdosfs now generates the extended bootsector
7 (superblock) format of DOS 3.3+, with support for volume ID's and

0 dosfsck, version 1
1 ==================
2
3 WARNING: This is ALPHA test software. Use at your own risk.
4
5 dosfsck is the Linux equivalent of PC/MS-DOS' CHKDSK. It checks the
6 consistency of PC/MS-DOS filesystems and optionally tries to repair
7 them. The tests dosfsck performs are described in the man page.
8
9 dosfsck needs header files from dosfs.9 (or later) to compile.
10
11 Before using dosfsck to repair a filesystem that contains data of any
12 value, you should verify that dosfsck is able to correct all reported
13 errors. (Except fatal errors and those reported as unfixable, of
14 course.) In order to do this, run it with the -V option, e.g.
15
16 dosfsck -V /dev/sda1 (automatic check)
17 or dosfsck -V -r /dev/sda1 (interactive check and repair)
18
19 dosfsck will perform two passes: in the first pass, inconsistencies are
20 detected and a list of changes to correct the problems is generated. In
21 the second pass, those changes are applied whenever dosfsck reads data
22 from disk. Hence no fixable errors should be reported in the second
23 pass if the first pass was successful.
24
25 Please notify the author if fixable errors are reported in the second
26 pass.
27
28 After verifying that dosfsck appears to be able to perform the desired
29 operations, either confirm that you want the changes to be performed
30 (if dosfsck was started with -r) or re-run dosfsck with the -a option
31 (if it was started without -r).
32
33 Please send bug reports, comments, flames, etc. to

38 FAT32 and LFN support
39 =====================
40
41 I've finally implemented some of the new features of MS-DOS
42 filesystems: FAT32 and long filenames.
43
44 FAT32 is automatically detected and of course the different FAT
45 structure is handled. (Internally many changes were needed, so 32 bit
46 variables for all cluster numbers and 64 bit vars for offsets inside
47 the filesystem.) New checks for FAT32 are most notably on the backup
48 boot sector and the new info sector. Also the possibility that the
49 root directory resides in a cluster chain (instead of in a static
50 area) on FAT32 is handled.
51
52 dosfscheck also knows about VFAT long filenames now. It parses those
53 names and uses them in listings etc. when available. There are also
54 some checks on the (cruel) structure of how LFNs are stored and some
55 attempts to fix problems.

1 Atari format support
2 ====================
3
4 Both mkdosfs and dosfsck now can also handle the Atari variation of
5 the MS-DOS filesystem format. The Atari format has some minor
6 differences, some caused by the different machine architecture (m68k),
7 some being "historic" (Atari didn't change some things that M$
8 changed).
9
10 Both tools automatically select Atari format if they run on an Atari.
11 Additionally the -A switch toggles between Atari and MS-DOS format.
12 I.e., on an Atari it selects plain DOS format, on any other machine it
13 switches to Atari format.
14
15 The differences are in detail:
16
17 - Atari TOS doesn't like cluster sizes != 2, so the usual solution
18 for bigger partitions was to increase the logical sector size. So
19 mkdosfs can handle sector sizes != 512 now, you can also manually
20 select it with the -S option. On filesystems larger than approx. 32
21 MB, the sector size is automatically increased (stead of the
22 cluster size) to make the filesystem fit. mkdosfs will always use 2
23 sectors per cluster (also with the floppy standard configurations),
24 except when directed otherwise on the command line.
25
26 - From the docs, all values between 0xfff8 and 0xffff in the FAT mark
27 an end-of-file. However, DOS usually uses 0xfff8 and Atari 0xffff.
28 This seems to be only an consmetic difference. At least TOS doesn't
29 complain about 0xffff EOF marks. Don't know what DOS thinks of
30 0xfff8 :-) Anyway, both tools use the EOF mark common to the
31 system (DOS/Atari).
32
33 - Something similar of the bad cluster marks: On Atari the FAT values
34 0xfff0 to 0xfff7 are used for this, under DOS only 0xfff7 (the
35 others can be normal cluster numbers, allowing 7 more clusters :-)
36 However, both systems usually mark with 0xfff7. Just dosfsck has to
37 interpret 0xfff0...0xfff7 differently.
38
39 - Some fields in the boot sector are interpreted differently. For
40 example, Atari has a disk serial number (used to aid disk change
41 detection) where DOS stores the system name; the 'hidden' field is
42 32 bit for DOS, but 16 bit for Atari, and there's no 'total_sect'
43 field; the 12/16 bit FAT decision is different: it's not based on
44 the number of clusters, but always FAT12 on floppies and FAT16 on
45 hard disks. mkdosfs nows about these differences and constructs the
46 boot sector accordingly.
47
48 - In dosfsck, the boot sector differences also have to known, to not
49 warn about things that are no error on Atari. In addition, most
50 Atari formatting tools fill the 'tracks' and 'heads' fields with 0
51 for hard disks, because they're meaningless on SCSI disks (Atari
52 has/had no IDE). Due to this, the check that they should be
53 non-zero is switched off.
54
55 - Under Atari TOS, some other characters are illegal in filenames:
56 '<', '>', '|', '"', and ':' are allowed, but all non-ASCII chars
57 (codes >= 128) are forbidden.

0 mkdosfs - Make DOS filesystem utilty.
1
2
3 I wrote this, partially to complement the dosfsck utility written by Werner
4 Almesberger (who graciously gave me some pointers when I asked for some
5 advice about writing this code), and also to avoid me having to boot DOS
6 just to create data partitions (I use Linux to back up DOS :-) ).
7
8 The code is really derived from Remy Card's mke2fs utility - I used this as a
9 framework, although all of the filesystem specific stuff was removed and the
10 DOS stuff inserted. I believe originally mke2fs was based on Linus' mkfs
11 code, hence the acknowledgements in the source code.
12
13 Neither Remy nor Linus have had any involvement with mkdosfs, so if there are
14 any bugs they're almost certainly "all my own work".
15
16 The code has been available for ftp since 1st September 1993, and I have yet
17 to receive any bug reports from users. I don't know of any bugs, but if you
18 do find a bug or have any constructive comments, please mail me!
19
20 The only bug I found with version 0.1 was an obscure fault that could lead
21 to an invalid (for MS-DOS, not Linux's dos fs) number of sectors used in the
22 file allocation table(s).

29 FAT32 support
30 =============
31
32 mkdosfs now can also create filesystems in the new FAT32 format. To do
33 this, give mkdosfs a "-F 32" option. FAT32 isn't selected
34 automatically (yet), even if very large clusters are needed with
35 FAT16. With FAT32 you have two additional options, -R to select the
36 number of reserved sectors (usually 32), and -b to select the location
37 of the backup boot sector (default 6). Of course such a backup is
38 created, as well as the new info sector. On FAT32, the root directory
39 is always created as a cluster chain. Sorry, there's no switch to
40 generate an old static root dir.
41
42 One bigger bug fix besides FAT32 was to reject filesystems that need a
43 16 bit FAT to fit all possible clusters, but the bigger FAT needs some
44 more sectors, so the total number of clusters drop below the border
45 where MS-DOS expects a 12 bit FAT. So such filesystems would be FAT16,
46 but interpreted as FAT32 by DOS. The fix is to reduce filesystem size
47 a bit.

5 template for generating boot sectors. This way, you can, e.g., make
6 bootable DOS disks.

8 Addendum: Don't know if that's so wise... There are really many
9 variants of DOS/Windows bootcode out in the wild, and the code is
10 proprietary, too.

29 \fBfsck.fat\fP \- check and repair MS\-DOS filesystems
30
31 .SH SYNOPSIS
32 \fBfsck.fat\fP|\fBfsck.msdos\fP|\fBfsck.vfat\fP [\-aAflnprtvVwy] [\-d \fIPATH\fP \-d\ \&\fI...\fP] [\-u\ \fIPATH\fP \-u \fI...\fP] \fIDEVICE\fP
33
34 .SH DESCRIPTION
35 \fBfsck.fat\fP verifies the consistency of MS\-DOS filesystems and optionally
36 tries to repair them.
37 .PP
38 The following filesystem problems can be corrected (in this order):
39 .IP * 4
40 FAT contains invalid cluster numbers. Cluster is changed to EOF.
41 .IP * 4
42 File's cluster chain contains a loop. The loop is broken.
43 .IP * 4
44 Bad clusters (read errors). The clusters are marked bad and they are removed
45 from files owning them. This check is optional.
46 .IP * 4
47 Directories with a large number of bad entries (probably corrupt). The
48 directory can be deleted.
49 .IP * 4
50 Files . and .. are non\-directories. They can be deleted or renamed.
51 .IP * 4
52 Directories . and .. in root directory. They are deleted.
53 .IP * 4
54 Bad filenames. They can be renamed.
55 .IP * 4
56 Duplicate directory entries. They can be deleted or renamed.
57 .IP * 4
58 Directories with non\-zero size field. Size is set to zero.
59 .IP * 4
60 Directory . does not point to parent directory. The start pointer is
61 adjusted.
62 .IP * 4
63 Directory .. does not point to parent of parent directory. The start pointer
64 is adjusted.
65 .IP * 4
66 Start cluster number of a file is invalid. The file is truncated.
67 .IP * 4
68 File contains bad or free clusters. The file is truncated.
69 .IP * 4
70 File's cluster chain is longer than indicated by the size fields. The file
71 is truncated.
72 .IP * 4
73 Two or more files share the same cluster(s). All but one of the files are
74 truncated. If the file being truncated is a directory file that has already
75 been read, the filesystem check is restarted after truncation.
76 .IP * 4
77 File's cluster chain is shorter than indicated by the size fields. The file
78 is truncated.
79 .IP * 4
80 Clusters are marked as used but are not owned by a file. They are marked as
81 free.
82 .PP
83 Additionally, the following problems are detected, but not repaired:
84 .IP * 4
85 Invalid parameters in boot sector.
86 .IP * 4
87 Absence of . and .. entries in non\-root directories
88 .PP
89 When \fBfsck.fat\fP checks a filesystem, it accumulates all changes in memory
90 and performs them only after all checks are complete. This can be disabled
91 with the \fB\-w\fP option.
92
93 .SH OPTIONS
94 .IP \fB\-a\fP 4
95 Automatically repair the filesystem. No user intervention is
96 necessary. Whenever there is more than one method to solve a problem, the
97 least destructive approach is used.
98 .IP \fB\-A\fP 4
99 Use Atari variation of the MS\-DOS filesystem. This is default if \fBfsck.fat\fP
100 is run on an Atari, then this option turns off Atari format. There are some
101 minor differences in Atari format: Some boot sector fields are interpreted
102 slightly different, and the special FAT entries for end\-of\-file and bad
103 cluster can be different. Under MS\-DOS 0xfff8 is used for EOF and Atari
104 employs 0xffff by default, but both systems recognize all values from
105 0xfff8...0xffff as end\-of\-file. MS\-DOS uses only 0xfff7 for bad clusters,
106 where on Atari values 0xfff0...0xfff7 are for this purpose (but the standard
107 value is still 0xfff7).
108 .IP \fB\-b\fP 4
109 Make read\-only boot sector check.
110 .IP \fB\-d\fP 4
111 Delete the specified file. If more that one file with that name exists, the
112 first one is deleted.
113 .IP \fB\-f\fP 4
114 Salvage unused cluster chains to files. By default, unused clusters are
115 added to the free disk space except in auto mode (\fB\-a\fP).
116 .IP \fB\-l\fP 4
117 List path names of files being processed.
118 .IP \fB\-n\fP 4
119 No\-operation mode: non\-interactively check for errors, but don't write
120 anything to the filesystem.
121 .IP \fB\-p\fP 4
122 Same as (\fB\-a\fP), for compatibility with other *fsck.
123 .IP \fB\-r\fP 4
124 Interactively repair the filesystem. The user is asked for advice whenever
125 there is more than one approach to fix an inconsistency.
126 .IP \fB\-t\fP 4
127 Mark unreadable clusters as bad.
128 .IP \fB\-u\fP 4
129 Try to undelete the specified file. \fBfsck.fat\fP tries to allocate a chain of
130 contiguous unallocated clusters beginning with the start cluster of the
131 undeleted file.
132 .IP \fB\-v\fP 4
133 Verbose mode. Generates slightly more output.
134 .IP \fB\-V\fP 4
135 Perform a verification pass. The filesystem check is repeated after the
136 first run. The second pass should never report any fixable errors. It may
137 take considerably longer than the first pass, because the first pass may
138 have generated long list of modifications that have to be scanned for each
139 disk read.
140 .IP \fB\-w\fP 4
141 Write changes to disk immediately.
142 .IP \fB\-y\fP 4
143 Same as \fB\-a\fP (automatically repair filesystem) for compatibility with other
144 fsck tools.
145 .PP
146 \fBNote:\fP If \fB\-a\fP and \fB\-r\fP are absent, the filesystem is only checked, but
147 not repaired.
148
149 .SH "EXIT STATUS"
150 .IP 0 4
151 No recoverable errors have been detected.
152 .IP 1 4
153 Recoverable errors have been detected or \fBfsck.fat\fP has discovered an
154 internal inconsistency.
155 .IP 2 4
156 Usage error. \fBfsck.fat\fP did not access the filesystem.
157
158 .SH FILES
159 .IP "fsck0000.rec, fsck0001.rec, ..." 4
160 When recovering from a corrupted filesystem, \fBfsck.fat\fP dumps recovered
161 data into files named 'fsckNNNN.rec' in the top level directory of the
162 filesystem.
163
164 .SH BUGS
165 Does not create . and .. files where necessary. Does not remove entirely
166 empty directories. Should give more diagnostic messages. Undeleting files
167 should use a more sophisticated algorithm.

39
40 .SH DESCRIPTION
41 \fBmkfs.fat\fP is used to create an MS\-DOS filesystem under Linux on a device
42 (usually a disk partition). \fIdevice\fP is the special file corresponding to
43 the device (e.g /dev/sdXX). \fIblock\-count\fP is the number of blocks on the
44 device. If omitted, \fBmkfs.fat\fP automatically determines the filesystem
45 size.
46
47 .SH OPTIONS
48 .IP \fB\-a\fP 4
49 Normally, for any filesystem except very small ones, \fBmkfs.fat\fP will align
50 all the data structures to cluster size, to make sure that as long as the
51 partition is properly aligned, so will all the data structures in the
52 filesystem. This option disables alignment; this may provide a handful of
53 additional clusters of storage at the expense of a significant performance
54 degradation on RAIDs, flash media or large\-sector hard disks.
55 .IP "\fB \-A\fP" 4
56 Use Atari variation of the MS\-DOS filesystem. This is default if \fBmkfs.fat\fP
57 is run on an Atari, then this option turns off Atari format. There are some
58 differences when using Atari format: If not directed otherwise by the user,
59 \fBmkfs.fat\fP will always use 2 sectors per cluster, since GEMDOS doesn't like
60 other values very much. It will also obey the maximum number of sectors
61 GEMDOS can handle. Larger filesystems are managed by raising the logical
62 sector size. Under Atari format, an Atari\-compatible serial number for the
63 filesystem is generated, and a 12 bit FAT is used only for filesystems that
64 have one of the usual floppy sizes (720k, 1.2M, 1.44M, 2.88M), a 16 bit FAT
65 otherwise. This can be overridden with the \fB\-F\fP option. Some PC\-specific
66 boot sector fields aren't written, and a boot message (option \fB\-m\fP) is
67 ignored.
68 .IP "\fB\-b\fP \fIsector\-of\-backup\fP" 4
69 Selects the location of the backup boot sector for FAT32. Default depends on
70 number of reserved sectors, but usually is sector 6. The backup must be
71 within the range of reserved sectors.
72 .IP \fB\-c\fP 4
73 Check the device for bad blocks before creating the filesystem.
74 .IP \fB\-C\fP 4
75 Create the file given as \fIdevice\fP on the command line, and write the
76 to\-be\-created filesystem to it. This can be used to create the new
77 filesystem in a file instead of on a real device, and to avoid using \fBdd\fP
78 in advance to create a file of appropriate size. With this option, the
79 \fIblock\-count\fP must be given, because otherwise the intended size of the
80 filesystem wouldn't be known. The file created is a sparse file, which
81 actually only contains the meta\-data areas (boot sector, FATs, and root
82 directory). The data portions won't be stored on the disk, but the file
83 nevertheless will have the correct size. The resulting file can be copied
84 later to a floppy disk or other device, or mounted through a loop device.
85 .IP "\fB\-D\fP \fIdrive\-number\fP" 4
86 Specify the BIOS drive number to be stored in the FAT boot sector. This
87 value is usually 0x80 for hard disks and 0x00 for floppy devices or
88 partitions to be used for floppy emulation.
89 .IP "\fB\-f\fP \fInumber\-of\-FATs\fP" 4
90 Specify the number of file allocation tables in the filesystem. The default
91 is 2. Currently the Linux MS\-DOS filesystem does not support more than 2
92 FATs.
93 .IP "\fB\-F\fP \fIFAT\-size\fP" 4
94 Specifies the type of file allocation tables used (12, 16 or 32 bit). If
95 nothing is specified, \fBmkfs.fat\fP will automatically select between 12, 16
96 and 32 bit, whatever fits better for the filesystem size.
97 .IP "\fB\-h\fP \fInumber\-of\-hidden\-sectors\fP" 4
98 Select the number of hidden sectors in the volume. Apparently some digital
99 cameras get indigestion if you feed them a CF card without such hidden
100 sectors, this option allows you to satisfy them.
101 .IP "\fB\-i\fP \fIvolume\-id\fP" 4
102 Sets the volume ID of the newly created filesystem; \fIvolume\-id\fP is a 32\-bit
103 hexadecimal number (for example, 2e24ec82). The default is a number which
104 depends on the filesystem creation time.
105 .IP \fB\-I\fP 4
106 It is typical for fixed disk devices to be partitioned so, by default, you
107 are not permitted to create a filesystem across the entire
108 device. \fBmkfs.fat\fP will complain and tell you that it refuses to work. This
109 is different when using MO disks. One doesn't always need partitions on MO
110 disks. The filesystem can go directly to the whole disk. Under other OSes
111 this is known as the 'superfloppy' format. This switch will force
112 \fBmkfs.fat\fP to work properly.
113 .IP "\fB\-l\fP \fIfilename\fP" 4
114 Read the bad blocks list from \fIfilename\fP.
115 .IP "\fB\-m\fP \fImessage\-file\fP" 4
116 Sets the message the user receives on attempts to boot this filesystem
117 without having properly installed an operating system. The message file must
118 not exceed 418 bytes once line feeds have been converted to carriage
119 return\-line feed combinations, and tabs have been expanded. If the filename
120 is a hyphen (\-), the text is taken from standard input.
121 .IP "\fB\-M\fP \fIFAT\-media\-type\fP" 4
122 Specify the media type to be stored in the FAT boot sector. This value is
123 usually 0xF8 for hard disks and has a value from 0xF9 to 0xFF for floppies

23 .SH NAME
24 \fBfsck.fat\fR \- check and repair MS\-DOS filesystems
25
26 .SH SYNOPSIS
27 \fBfsck.fat\fR|\fBfsck.msdos\fR|\fBfsck.vfat\fR [\-aAflnprtvVwy] [\-d \fIPATH\fR \-d\ \fI...\fR] [\-u\ \fIPATH\fR \-u \fI...\fR] \fIDEVICE\fR
28
29 .SH DESCRIPTION
30 \fBfsck.fat\fR verifies the consistency of MS\-DOS filesystems and optionally tries to repair them.
31 .PP
32 The following filesystem problems can be corrected (in this order):
33 .IP "*" 4
34 FAT contains invalid cluster numbers. Cluster is changed to EOF.
35 .IP "*" 4
36 File's cluster chain contains a loop. The loop is broken.
37 .IP "*" 4
38 Bad clusters (read errors). The clusters are marked bad and they are removed from files owning them. This check is optional.
39 .IP "*" 4
40 Directories with a large number of bad entries (probably corrupt). The directory can be deleted.
41 .IP "*" 4
42 Files . and .. are non\-directories. They can be deleted or renamed.
43 .IP "*" 4
44 Directories . and .. in root directory. They are deleted.
45 .IP "*" 4
46 Bad filenames. They can be renamed.
47 .IP "*" 4
48 Duplicate directory entries. They can be deleted or renamed.
49 .IP "*" 4
50 Directories with non\-zero size field. Size is set to zero.
51 .IP "*" 4
52 Directory . does not point to parent directory. The start pointer is adjusted.
53 .IP "*" 4
54 Directory .. does not point to parent of parent directory. The start pointer is adjusted.
55 .IP "*" 4
56 Start cluster number of a file is invalid. The file is truncated.
57 .IP "*" 4
58 File contains bad or free clusters. The file is truncated.
59 .IP "*" 4
60 File's cluster chain is longer than indicated by the size fields. The file is truncated.
61 .IP "*" 4
62 Two or more files share the same cluster(s). All but one of the files are truncated. If the file being truncated is a directory file that has already been read, the filesystem check is restarted after truncation.
63 .IP "*" 4
64 File's cluster chain is shorter than indicated by the size fields. The file is truncated.
65 .IP "*" 4
66 Clusters are marked as used but are not owned by a file. They are marked as free.
67 .PP
68 Additionally, the following problems are detected, but not repaired:
69 .IP "*" 4
70 Invalid parameters in boot sector.
71 .IP "*" 4
72 Absence of . and .. entries in non\-root directories
73 .PP
74 When \fBfsck.fat\fR checks a filesystem, it accumulates all changes in memory and performs them only after all checks are complete. This can be disabled with the \fB\-w\fR option.
75
76 .SH OPTIONS
77 .IP "\fB\-a\fR" 4
78 Automatically repair the filesystem. No user intervention is necessary. Whenever there is more than one method to solve a problem, the least destructive approach is used.
79 .IP "\fB\-A\fR" 4
80 Use Atari variation of the MS\-DOS filesystem. This is default if \fBfsck.fat\fR is run on an Atari, then this option turns off Atari format. There are some minor differences in Atari format: Some boot sector fields are interpreted slightly different, and the special FAT entries for end\-of\-file and bad cluster can be different. Under MS\-DOS 0xfff8 is used for EOF and Atari employs 0xffff by default, but both systems recognize all values from 0xfff8...0xffff as end\-of\-file. MS\-DOS uses only 0xfff7 for bad clusters, where on Atari values 0xfff0...0xfff7 are for this purpose (but the standard value is still 0xfff7).
81 .IP "\fB-b\fR" 4
82 Make read-only boot sector check.
83 .IP "\fB\-d\fR" 4
84 Delete the specified file. If more that one file with that name exists, the first one is deleted.
85 .IP "\fB\-f\fR" 4
86 Salvage unused cluster chains to files. By default, unused clusters are added to the free disk space except in auto mode (\fB\-a\fR).
87 .IP "\fB\-l\fR" 4
88 List path names of files being processed.
89 .IP "\fB\-n\fR" 4
90 No\-operation mode: non\-interactively check for errors, but don't write
91 anything to the filesystem.
92 .IP "\fB\-p\fR" 4
93 Same as (\fB\-a\fR), for compatibility with other *fsck.
94 .IP "\fB\-r\fR" 4
95 Interactively repair the filesystem. The user is asked for advice whenever
96 there is more than one approach to fix an inconsistency.
97 .IP "\fB\-t\fR" 4
98 Mark unreadable clusters as bad.
99 .IP "\fB\-u\fR" 4
100 Try to undelete the specified file. \fBfsck.fat\fR tries to allocate a chain of contiguous unallocated clusters beginning with the start cluster of the undeleted file.
101 .IP "\fB\-v\fR" 4
102 Verbose mode. Generates slightly more output.
103 .IP "\fB\-V\fR" 4
104 Perform a verification pass. The filesystem check is repeated after the first run. The second pass should never report any fixable errors. It may take considerably longer than the first pass, because the first pass may have generated long list of modifications that have to be scanned for each disk read.
105 .IP "\fB\-w\fR" 4
106 Write changes to disk immediately.
107 .IP "\fB\-y\fR" 4
108 Same as \fB\-a\fR (automatically repair filesystem) for compatibility with other fsck tools.
109 .PP
110 \fBNote:\fR If \fB\-a\fR and \fB\-r\fR are absent, the filesystem is only checked, but not repaired.
111
112 .SH "EXIT STATUS"
113 .IP "0" 4
114 No recoverable errors have been detected.
115 .IP "1" 4
116 Recoverable errors have been detected or \fBfsck.fat\fR has discovered an internal inconsistency.
117 .IP "2" 4
118 Usage error. \fBfsck.fat\fR did not access the filesystem.
119
120 .SH FILES
121 .IP "fsck0000.rec, fsck0001.rec, ..." 4
122 When recovering from a corrupted filesystem, \fBfsck.fat\fR dumps recovered data into files named 'fsckNNNN.rec' in the top level directory of the filesystem.
123
124 .SH BUGS
125 Does not create . and .. files where necessary. Does not remove entirely empty directories. Should give more diagnostic messages. Undeleting files should use a more sophisticated algorithm.

23 .SH NAME
24 \fBmkfs.fat\fR \- create an MS-DOS filesystem under Linux
25
26 .SH SYNOPSIS
27 \fBmkfs.fat\fR [\fB\-a\fR] [\fB\-A\fR] [\fB\-b\fR \fIsector-of-backup\fR] [\fB\-c\fR] [\fB\-l\fR \fIfilename\fR] [\fB\-C\fR] [\fB\-f\fR \fInumber-of-FATs\fR] [\fB\-F\fR \fIFAT-size] [\fB\-h\fR \fInumber-of-hidden-sectors\fR] [\fB\-i\fR \fIvolume-id\fR] [\fB\-I\fR] [\fB\-m\fR \fImessage-file\fR] [\fB\-n\fR \fIvolume-name\fR] [\fB\-r\fR \fIroot-dir-entries\fR] [\fB\-R\fR \fInumber-of-reserved-sectors\fR] [\fB\-s\fR \fIsectors-per-cluster\fR] [\fB\-S \fIlogical-sector-size\fR] [\fB\-D\fR \fIdrive-number\fR] [\fB\-M \fIFAT-media-type\fR] [\fB\-v\fR] \fIdevice\fR [\fIblock-count\fR]
28
29 .SH DESCRIPTION
30 \fBmkfs.fat\fR is used to create an MS-DOS filesystem under Linux on a device (usually a disk partition). \fIdevice\fR is the special file corresponding to the device (e.g /dev/sdXX). \fIblock-count\fR is the number of blocks on the device. If omitted, \fBmkfs.fat\fR automatically determines the filesystem size.
31
32 .SH OPTIONS
33 .IP "\fB\-a\fR" 4
34 Normally, for any filesystem except very small ones, \fBmkfs.fat\fR will align all the data structures to cluster size, to make sure that as long as the partition is properly aligned, so will all the data structures in the filesystem. This option disables alignment; this may provide a handful of additional clusters of storage at the expense of a significant performance degradation on RAIDs, flash media or large-sector hard disks.
35 .IP "\fB \-A\fR" 4
36 Use Atari variation of the MS-DOS filesystem. This is default if \fBmkfs.fat\fR is run on an Atari, then this option turns off Atari format. There are some differences when using Atari format: If not directed otherwise by the user, \fBmkfs.fat\fR will always use 2 sectors per cluster, since GEMDOS doesn't like other values very much. It will also obey the maximum number of sectors GEMDOS can handle. Larger filesystems are managed by raising the logical sector size. Under Atari format, an Atari-compatible serial number for the filesystem is generated, and a 12 bit FAT is used only for filesystems that have one of the usual floppy sizes (720k, 1.2M, 1.44M, 2.88M), a 16 bit FAT otherwise. This can be overridden with the \fB\-F\fR option. Some PC-specific boot sector fields aren't written, and a boot message (option \fB\-m\fR) is ignored.
37 .IP "\fB\-b\fR \fIsector-of-backup\fR" 4
38 Selects the location of the backup boot sector for FAT32. Default depends on number of reserved sectors, but usually is sector 6. The backup must be within the range of reserved sectors.
39 .IP "\fB\-c" 4
40 Check the device for bad blocks before creating the filesystem.
41 .IP "\fB\-C\fR" 4
42 Create the file given as \fIdevice\fR on the command line, and write the to-be-created filesystem to it. This can be used to create the new filesystem in a file instead of on a real device, and to avoid using \fBdd\fR in advance to create a file of appropriate size. With this option, the \fIblock-count\fR must be given, because otherwise the intended size of the filesystem wouldn't be known. The file created is a sparse file, which actually only contains the meta-data areas (boot sector, FATs, and root directory). The data portions won't be stored on the disk, but the file nevertheless will have the correct size. The resulting file can be copied later to a floppy disk or other device, or mounted through a loop device.
43 .IP "\fB\-D\fR \fIdrive-number\fR" 4
44 Specify the BIOS drive number to be stored in the FAT boot sector. This value is usually 0x80 for hard disks and 0x00 for floppy devices or partitions to be used for floppy emulation.
45 .IP "\fB\-f\fR \fInumber-of-FATs\fR" 4
46 Specify the number of file allocation tables in the filesystem. The default is 2. Currently the Linux MS-DOS filesystem does not support more than 2 FATs.
47 .IP "\fB\-F\fR \fIFAT-size\fR" 4
48 Specifies the type of file allocation tables used (12, 16 or 32 bit). If nothing is specified, \fBmkfs.fat\fR will automatically select between 12, 16 and 32 bit, whatever fits better for the filesystem size.
49 .IP "\fB\-h\fR \fInumber-of-hidden-sectors\fR" 4
50 Select the number of hidden sectors in the volume. Apparently some digital cameras get indigestion if you feed them a CF card without such hidden sectors, this option allows you to satisfy them.
51 .IP "\fB\-i\fR \fIvolume-id\fR" 4
52 Sets the volume ID of the newly created filesystem; \fIvolume-id\fR is a 32-bit hexadecimal number (for example, 2e24ec82). The default is a number which depends on the filesystem creation time.
53 .IP "\fB\-I\fR" 4
54 It is typical for fixed disk devices to be partitioned so, by default, you are not permitted to create a filesystem across the entire device. \fBmkfs.fat\fR will complain and tell you that it refuses to work. This is different when using MO disks. One doesn't always need partitions on MO disks. The filesystem can go directly to the whole disk. Under other OSes this is known as the 'superfloppy' format. This switch will force \fBmkfs.fat\fR to work properly.
55 .IP "\fB\-l\fR \fIfilename\fR" 4
56 Read the bad blocks list from \fIfilename\fR.
57 .IP "\fB\-m\fR \fImessage-file\fR" 4
58 Sets the message the user receives on attempts to boot this filesystem without having properly installed an operating system. The message file must not exceed 418 bytes once line feeds have been converted to carriage return-line feed combinations, and tabs have been expanded. If the filename is a hyphen (-), the text is taken from standard input.
59 .IP "\fB\-M\fR \fIFAT-media-type\fR" 4
60 Specify the media type to be stored in the FAT boot sector. This value is usually 0xF8 for hard disks and has a value from 0xF9 to 0xFF for floppies or partitions to be used for floppy emulation.
61 .IP "\fB\-n\fR \fIvolume-name\fR" 4
62 Sets the volume name (label) of the filesystem. The volume name can be up to 11 characters long. The default is no label.
63 .IP "\fB\-r\fR \fIroot-dir-entries\fR" 4
64 Select the number of entries available in the root directory. The default is 112 or 224 for floppies and 512 for hard disks.
65 .IP "\fB\-R\fR \fInumber-of-reserved-sectors\fR" 4
66 Select the number of reserved sectors. With FAT32 format at least 2 reserved sectors are needed, the default is 32. Otherwise the default is 1 (only the boot sector).
67 .IP "\fB\-s\fR \fIsectors-per-cluster\fR" 4
68 Specify the number of disk sectors per cluster. Must be a power of 2, i.e. 1, 2, 4, 8, ... 128.
69 .IP "\fB\-S\fR \fIlogical-sector-size\fR" 4
70 Specify the number of bytes per logical sector. Must be a power of 2 and greater than or equal to 512, i.e. 512, 1024, 2048, 4096, 8192, 16384, or 32768.
71 .IP "\fB\-v\fR" 4
72 Verbose execution.

26 /* Description: Utility to allow an MS-DOS filesystem to be created
27 under Linux. A lot of the basic structure of this program has been
28 borrowed from Remy Card's "mke2fs" code.
29
30 As far as possible the aim here is to make the "mkfs.fat" command
31 look almost identical to the other Linux filesystem make utilties,
32 eg bad blocks are still specified as blocks, not sectors, but when
33 it comes down to it, DOS is tied to the idea of a sector (512 bytes
34 as a rule), and not the block. For example the boot block does not
35 occupy a full cluster.
