    1 dosfstools 4.2 - released 2021-01-31
    2 ====================================
    4 fatlabel now accepts two new options. When given the -i or --volume-id option,
    5 fatlabel changes to an alternate mode where it displays or changes the volume
    6 serial number instead of the volume label. With the -r or --reset option, it
    7 will remove the label or (in the alternate mode) generate a new volume serial
    8 number.
   10 The user prompting for interactive fsck has been overhauled. Now it will
   11 directly react to a pressed key without the user having to additionally press
   12 enter. The changed prompting is also consistently repeating the prompt when
   13 invalid input is given.
   15 The legacy check whether it is running on Atari hardware when compiled for 68k
   16 in order to automatically switch to Atari mode is now disabled by default. It
   17 can be compiled in with the new configure switch --enable-atari-check.
   19 Both mkfs and fsck now have a new option --variant=TYPE where TYPE can be
   20 'standard' or 'atari' to explicitly select one of those variants rather than
   21 having to toggle between them with -A.
   23 fsck, mkfs and fatlabel were fixed to process volume label correctly. Previously
   24 there were many issues during processing labels. Fixes issues are: leading byte
   25 0xE5 of root label needs to be handled in special way, label cannot contain some
   26 special characters, label itself is stored according to the current DOS codepage
   27 which may be specified by a new --codepage option. fatlabel now reads volume
   28 label only from the root directory to be compatible with existing systems like
   29 MS-DOS 5.00, MS-DOS 6.22, MS-DOS 7.10, Windows 98, Windows XP, Windows 7, 8, 10
   30 and also with the Linux mlabel from mtools project. fsck was extended to fix
   31 incorrect volume labels and ensure that volume label from the root directory is
   32 same as the volume label stored in boot sector. Old versions of dosfslabel read
   33 label only from the boot sector. So with all these changes fsck now ensures
   34 compatibility with both MS-DOS/Windows and old Linux/dosfslabel world.
   36 fsck now allows spaces in the middle of SFNs. Previous behavior (when spaces
   37 are disallowed) can be achieved by a new option -S.
   39 Both mkfs and fsck now have fixed Year 2038 Bug. mkfs may still set filesystem
   40 timestamp to 1980-01-01 00:00:00 (beginning of the FAT era) in case operating
   41 system has Year 2038 Bug and cannot provide current time in time_t variable.
   43 Some memory leaks were fixed in fatlabel and fsck to make valgrind happy.
   45 Processing of command line arguments in all tools were fixed to ensure that
   46 invalid options are not accepted anymore and proper error message is thrown
   47 instead of trying to continue with uninitialized or undefined value.
   49 In fsck and fatlabel were fixed issues that faulty filesystems were able to
   50 trigger integer overflows during reading them.
   52 mkfs now has a new option --offset for specifying offset at which filesystem
   53 would start. This is useful when formatting FAT filesystem on disk image with
   54 MBR table without need to use loopback kernel driver with partx to access only
   55 specific partition.
   57 All tools now can be compiled without iconv library and in this case they
   58 support only CP850 codepage which is integrated into tools. This internal
   59 CP850 codepage can be used also when tools were compiled with iconv library
   60 which do not support CP850 (e.g. iconv from GNU libc without installed gconv
   61 shared libraries).
   63 Manual pages were updated to clarify some ambiguous options and descriptions.
   64 fatlabel has a new section with details about volume label and codepage issues.
   66 mkfs now has a new option --mbr which fills (fake) MBR table with one partition
   67 which spans whole disk device. This (fake) MBR table is needed only for
   68 non-removable disks used on Microsoft Windows systems and only when formatting
   69 whole unpartitioned disk.
   71 mkfs now calculates CHS geometry according to the SD Card Part 2 File System
   72 Specification. For SD cards with more than 256MB capacity is this new CHS
   73 calculation same as CHS calculation defined for hard disks via LBA-Assist
   74 Translation. So CHS geometry calculation in mkfs is now compatible with both
   75 SD Card specification and also LBA-Assist Translation. Moreover mkfs now has
   76 also a new option -g for specifying CHS geometry manually if it is needed for
   77 compatibility with some SD card readers. CHS geometry is part of FAT boot
   78 sector which mkfs.fat must fill.
   80 fsck now checks for DOS Clean Shutdown bit and marks filesystem as clean after
   81 successful run. This is for compatibility with Microsft Windows 98 and also with
   82 Windows NT-based variants.
   84 Dependency on systemd/udev was completely removed from mkfs tool. But there is
   85 no lost or removed functionality. Existing systemd/udev code was rewritten to
   86 directly access sysfs and new implementation has less lines of code as previous
   87 implementation which used systemd/udev libraries.
   89 mkfs was fixed to setup FAT32 backup boot sector correctly.
   91 mkfs's -D option (BIOS drive number) was relaxed to support also higher level
   92 hard disk and floppy devices (second, third, ...).
   94 fsck now preserve reserved fields in info sector. They are used by other systems
   95 (e.g. FSIBOOT stage of lDOS boot32.asm), hence why are reserved.
   97 fsck was extended to check and fix that first two entires in directory
   98 structures are . and ..
  100 mkfs now aligns total number of sectors to be multiple of the value of sectors
  101 per track which is stored in FAT boot sector. This requirement is needed by DOS
  102 systems and also by Linux FAT tools from mtools project. Alignment can be turned
  103 off by -a option.
  105 mkfs is now able to calculate FAT32 cluster size also for disks which have
  106 sector size different than 512 bytes. Note that this calculation is not optimal.
  107 It is just first step which ensures that mkfs does not fail during formatting
  108 Native 4K disks.
  110 mkfs cluster calculation was fixed to correctly handle differences between
  111 FAT12 and FAT16 variants. mkfs now explicitly disallow to create FAT filesystem
  112 with 4085 or 4086 clusters because Windows fastfat.sys detects such filesystem
  113 as FAT12 but Linux msdos.ko/vfat.ko detects it as FAT16. mkfs now avoids this
  114 situation to happen by fully automatic increasing or decreasing cluster size.
  116 fsck now has a new option -F which can be used to specify FAT table used for
  117 reading whole FAT filesystem. It can be useful in situation when user wants
  118 to do recovery and filesystem repairing from second FAT table independently
  119 of what fsck thinks that is the best.
  121 fsck was extended to try fixing first FAT cluster but only when -F option is
  122 specified. Previously when first FAT cluster was broken, fsck just printed
  123 error: "Both FATs appear to be corrupt. Giving up." and failed.
  125 fatlabel was fixed to not call parts of fsck procedure and to not print
  126 warning or log messages on stdout as it conflicts with expected label
  127 output on stdout.
  129 A test suite was heavily extended and now it also checks that fsck repairs
  130 broken filesystem into the expected state.

  158 dosfstools 4.1 - released 2017-01-24
  159 ====================================
  161 A test suite is now included and can be run with "make check". The test suite
  162 requires xxd from the vim distribution to recreate image files from hexdumps and
  163 also adds a dependency on automake 1.11 or later for building from sources other
  164 than the release tarball.
  166 Now the default for mkfs for filesystems smaller than 512 MB is 64 heads / 32
  167 sectors to make the defaults a bit more in line with the old defaults used up to
  168 3.0.28.
  170 Other changes are fixes, some of them user visible, such as setting the sector
  171 size by command line option for mkfs working again after being broken in 4.0.
  173 Fixed a possible fatlabel crash when writing a label to an unlabelled filesystem
  174 and the given label contains printf style format specifiers.
  176 When circular cluster chains were detected and the -t option was not given, fsck
  177 used to truncate the file to zero length while not updating the free cluster
  178 count. This required a second fsck run to clear. Now it always truncates to the
  179 last cluster that begins the loop, as it is supposed to.
  181 The parsing of octal character specifications for filenames in the -u and -d
  182 options of fsck now works. It was broken in some ancient version and would
  183 always fail.
  186 dosfstools 4.0 - released 2016-05-06
  187 ====================================
  189 The programs are now portable to non-Linux operating systems. To that end, the
  190 build system has been converted to use autotools. There have been Linux
  191 specifics in a lot of places which have been either eliminated or should have
  192 equivalents so that it should now work in other Unix-like environments. It has
  193 been tested on FreeBSD and OS X.
  195 As part of making it portable all the code that assumed 8 bit major/minor
  196 numbers - and in fact masked out all other bits - has been cleaned up. Now
  197 mkfs.vfat should not misidentify devices anymore and require the -I option to
  198 override. The new device probing uses libudev (if available) to collect more
  199 information.
  201 Fixed data corruption errors in fsck.fat: Writing to the third to last cluster
  202 on FAT12 with an odd number of clusters would corrupt the following cluster. In
  203 mkfs.fat, long existing bugs in bad cluster marking (from scanning or user
  204 supplied bad blocks list) were fixed so that it actually marks the correct
  205 clusters.
  207 The automatic alignment of data clusters that was added in 3.0.8 and broken for
  208 FAT32 starting with 3.0.20 has been reinstated. If you need to create file
  209 systems for finicky devices that have broken FAT implementations use the option
  210 -a to disable alignment.
  213 dosfstools 3.0.28 - released 2015-05-16
  214 =======================================
  216 The major user visible change in this release is that fsck.fat now defaults to
  217 interactive repair mode which previously had to be selected with -r. The
  218 previous default of a read only check mode was confusing to users who had to
  219 repeat a potentially lengthy fsck.fat run with the right option in order to
  220 actually fix their file system. It was also pointless – the interactive repair
  221 mode already won't write anything without asking for confirmation.
  223 mkfs.fat now allows choosing 0xF0 as the media byte which was previously
  224 rejected.
  226 mkfs.fat now supports the --invariant option to facilitate testing mkfs.fat
  227 itself. It will reproducibly generate filesystems without random or time based
  228 differences between them when all else is identical.
  230 Bugs fixed in fsck.fat are a read one byte beyond the end of an allocated array
  231 when checking some FAT12 filesystems, and checking that the first cluster of a
  232 file as specified in the directory entry is not 1. Previously it could attempt
  233 to follow a block chain starting on cluster 1 and segfault when the conditions
  234 are right.
  237 dosfstools 3.0.27 - released 2014-11-12
  238 =======================================
  240 This is a pure bug fix release. The major bugs fixed:
  242 * fatlabel did not recognize long file names and mistook long file name
  243   segments in the root directory for labels. This caused output of garbage when
  244   asked to print the label and damage to the root directory (loss of long file
  245   name after fsck) when used to set the label.
  247 * A fsck.fat check introduced in 3.0.26 triggered use of uninitialized fields
  248   in the constructed root directory entry, which randomly caused the code
  249   checking file names to consider the empty "file name" of the root directory
  250   to be bad:
  252     $ /sbin/fsck.fat -y bad.img
  253     fsck.fat 3.0.26 (2014-03-07)
  254     /
  255     Bad short file name ().
  256     Auto-renaming it.
  257     Renamed to
  258     bad.img: 14 files, 19388/403266 clusters
  260 * And finally fsck.fat will not print the version string anymore every time the
  261   -v option is encountered.
