| 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. | |

| 23 | -------------- | |
| 24 | ||
| 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. | |

| 0 | Changes from version 0 to 1 | |
| 1 | =========================== | |
| 2 | ||
| 3 | - fixed an off-by-two error in check.c:check_file | |
| 4 | - fixed marking clusters bad in fat.c:set_fat | |
| 5 | - fat.c:reclaim_free was also reclaiming bad clusters. | |
| 6 | - fixed many incorrect byte sex conversions in check.c and fat.c | |
| 7 | - -t and -w now require -a or -r | |
| 8 | - added option -d to drop files. | |
| 9 | - added option -u to try to "undelete" non-directory files. |
| 0 | version 2.11 | |
| 1 | ============ | |
| 2 | ||
| 3 | - all: don't use own llseek() anymore, glibc lseek() does everything we need | |
| 4 | - dosfsck: lfn.c: avoid segfault | |
| 5 | - dosfsck: check.c, lfn.c: check for orphaned LFN slots | |
| 6 | - dosfsck: check.c alloc_rootdir_entry(): set owner of newly alloced clusters | |
| 7 | - dosfsck: dosfsck.h: better use <byteswap.h> for byte swapping | |
| 8 | - dosfsck: io.c: added code for real DOS | |
| 9 | - mkdosfs: raised FAT12_THRESHOLD from 4078 to 4085, introduced MIN_CLUST_32 | |
| 10 | - mkdosfs: fix loop device size | |
| 11 | - mkdosfs: by default, use FAT32 on devices >= 512MB | |
| 12 | - mkdosfs: fix a memory leak (blank_sector) | |
| 13 | - mkdosfs: fix parsing of number of blocks on command line, so that numbers | |
| 14 | >2G can be used | |
| 15 | - mkdosfs: add 'b' to getopt() string so this option can be used :) | |
| 16 | - mkdosfs: fix parsing of -i arg (should be unsigned) | |
| 17 | - mkdosfs: change default permissions of created images (-C) to 0666 & ~umask | |
| 18 | - mkdosfs: relax geometry check: if HDIO_GETGEO fails, print a warning and | |
| 19 | default to H=255,S=63 | |
| 20 | - dosfsck: new option -n (no-op): just check non-interactively, but | |
| 21 | don't write anything to filesystem | |
| 22 | - A few #include changes to support compilation with linux 2.6 | |
| 23 | headers (thanks to Jim Gifford <jim@jg555.com>) | |
| 24 | - dosfsck: remove directory entries pointing to start cluster 0, if they're | |
| 25 | not "." or ".." entries that should actually point to the root dir | |
| 26 | (pointed out by Thomas Winkler <twinkler@sysgo.de>) | |
| 27 | - mkdosfs: new option -h to set number of hidden sectors | |
| 28 | (thanks to Godwin Stewart <gstewart@spamcop.net>) | |
| 29 | - all: updated my mail address everywhere... | |
| 30 | ||
| 31 | version 2.10 | |
| 32 | ============ | |
| 33 | ||
| 34 | - dosfsck: various 64-bit fixes and removed some warnings by Michal | |
| 35 | Cihar <mcihar@suse.cz> | |
| 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. | |
| 159 | ||

| 0 | 28th January 1995 H. Peter Anvin (hpa@yggdrasil.com) | |
| 1 | ||
| 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 | |
| 8 | volume labels (volume labels are also written to the root | |
| 9 | directory, as they should). | |
| 10 | ||
| 11 | 18th February 1994 Dave Hudson (dave@humbug.demon.co.uk) | |
| 12 | ||
| 13 | Released version 0.2 - clears a bug in the FAT sizing code. | |
| 14 | ||
| 15 | 1st September 1993 Dave Hudson (dave@humbug.demon.co.uk) | |
| 16 | ||
| 17 | Released version 0.1 - ALPHA release of mkdosfs |
| 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). | |

| 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. | |

| 2 | - dosfsck: Better checking of file times: ctime <= mtime <= atime | |
| 3 | ||
| 4 | - mkdosfs: If /etc/bootsect.dos (or similar) exists, use it as a | |
| 5 | template for generating boot sectors. This way, you can, e.g., make | |
| 6 | bootable DOS disks. | |
| 7 | ||
| 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. | |
| 11 | ||
| 12 | - dosfsck: read-only sector test (-t without -a or -r); just print | |
