Now it is no longer + necessary to change the number in multiple places for a release and the + man pages get the number substituted directly into them, making the + update-version.sh script and the VERSION file obsolete. + + The English man pages are moved back up one directory to mark their + status as the master copy for all translations. At the moment the po4a + translation infrastructure is defunct since it isn't integrated into + the automake environment yet. So far it hasn't been used, so that is + not an actual regression. + + The date in the man pages is not automatically updated anymore. This is + as it should be, since the date is supposed to signify the time of the + last nontrivial change and not the release date of the software. + + Signed-off-by: Andreas Bombe + +commit 85022fe (tag: v3.0.28) +Author: Andreas Bombe +Date: Sat May 16 02:56:17 2015 +0200 + + Releasing version 3.0.28. + + Signed-off-by: Andreas Bombe + commit ad1342e Author: Andreas Bombe Date: Sat May 16 02:10:18 2015 +0200 diff --git a/Makefile b/Makefile deleted file mode 100644 index 1593f3d..0000000 --- a/Makefile +++ /dev/null @@ -1,170 +0,0 @@ -# Makefile -# -# Copyright (C) 2008-2014 Daniel Baumann -# -# This program is free software: you can redistribute it and/or modify -# it under the terms of the GNU General Public License as published by -# the Free Software Foundation, either version 3 of the License, or -# (at your option) any later version. -# -# This program is distributed in the hope that it will be useful, -# but WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

To that end, the +build system has been converted to use autotools. There have been Linux +specifics in a lot of places which have been either eliminated or should have +equivalents so that it should now work in other Unix-like environments. It has +been tested on FreeBSD and OS X. + +As part of making it portable all the code that assumed 8 bit major/minor +numbers - and in fact masked out all other bits - has been cleaned up. Now +mkfs.vfat should not misidentify devices anymore and require the -I option to +override. The new device probing uses libudev (if available) to collect more +information. + +Fixed data corruption errors in fsck.fat: Writing to the third to last cluster +on FAT12 with an odd number of clusters would corrupt the following cluster. In +mkfs.fat, long existing bugs in bad cluster marking (from scanning or user +supplied bad blocks list) were fixed so that it actually marks the correct +clusters. + +The automatic alignment of data clusters that was added in 3.0.8 and broken for +FAT32 starting with 3.0.20 has been reinstated. If you need to create file +systems for finicky devices that have broken FAT implementations use the option +-a to disable alignment. + + +dosfstools 3.0.28 - released 2015-05-16 +======================================= + +The major user visible change in this release is that fsck.fat now defaults to +interactive repair mode which previously had to be selected with -r. The +previous default of a read only check mode was confusing to users who had to +repeat a potentially lengthy fsck.fat run with the right option in order to +actually fix their file system. It was also pointless – the interactive repair +mode already won't write anything without asking for confirmation. + +mkfs.fat now allows choosing 0xF0 as the media byte which was previously +rejected. + +mkfs.fat now supports the --invariant option to facilitate testing mkfs.fat +itself. It will reproducibly generate filesystems without random or time based +differences between them when all else is identical. + +Bugs fixed in fsck.fat are a read one byte beyond the end of an allocated array +when checking some FAT12 filesystems, and checking that the first cluster of a +file as specified in the directory entry is not 1. Previously it could attempt +to follow a block chain starting on cluster 1 and segfault when the conditions +are right. + + +dosfstools 3.0.27 - released 2014-11-12 +======================================= + +This is a pure bug fix release. The major bugs fixed: + +* fatlabel did not recognize long file names and mistook long file name + segments in the root directory for labels. This caused output of garbage when + asked to print the label and damage to the root directory (loss of long file + name after fsck) when used to set the label. + +* A fsck.fat check introduced in 3.0.26 triggered use of uninitialized fields + in the constructed root directory entry, which randomly caused the code + checking file names to consider the empty "file name" of the root directory + to be bad: + + $ /sbin/fsck.fat -y bad.img + fsck.fat 3.0.26 (2014-03-07) + / + Bad short file name (). + Auto-renaming it. + Renamed to + bad.img: 14 files, 19388/403266 clusters + +* And finally fsck.fat will not print the version string anymore every time the + -v option is encountered. diff --git a/README b/README new file mode 100644 index 0000000..8fe8249 --- /dev/null +++ b/README @@ -0,0 +1,39 @@ +dosfstools consists of the programs mkfs.fat, fsck.fat and fatlabel to create, +check and label file systems of the FAT family.

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. +.IP "\fB \-A\fR" 4 +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. +.IP "\fB\-b\fR \fISECTOR-OF-BACKUP\fR" 4 +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. +.IP "\fB\-c" 4 +Check the device for bad blocks before creating the filesystem. +.IP "\fB\-C\fR" 4 +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. +.IP "\fB\-D\fR \fIDRIVE-NUMBER\fR" 4 +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. +.IP "\fB\-f\fR \fINUMBER-OF-FATS\fR" 4 +Specify the number of file allocation tables in the filesystem. +The default is 2. +.IP "\fB\-F\fR \fIFAT-SIZE\fR" 4 +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. +.IP "\fB\-h\fR \fINUMBER-OF-HIDDEN-SECTORS\fR" 4 +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. +.IP "\fB\-i\fR \fIVOLUME-ID\fR" 4 +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. +.IP "\fB\-I\fR" 4 +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. +.IP "\fB\-l\fR \fIFILENAME\fR" 4 +Read the bad blocks list from \fIFILENAME\fR. +.IP "\fB\-m\fR \fIMESSAGE-FILE\fR" 4 +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. +.IP "\fB\-M\fR \fIFAT-MEDIA-TYPE\fR" 4 +Specify the media type to be stored in the FAT boot sector. +This value is usually 0xF8 for hard disks and is 0xF0 or a value from 0xF9 to +0xFF for floppies or partitions to be used for floppy emulation. +.IP "\fB\-n\fR \fIVOLUME-NAME\fR" 4 +Sets the volume name (label) of the filesystem. +The volume name can be up to 11 characters long. +The default is no label. +.IP "\fB\-r\fR \fIROOT-DIR-ENTRIES\fR" 4 +Select the number of entries available in the root directory. +The default is 112 or 224 for floppies and 512 for hard disks. +.IP "\fB\-R\fR \fINUMBER-OF-RESERVED-SECTORS\fR" 4 +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). +.IP "\fB\-s\fR \fISECTORS-PER-CLUSTER\fR" 4 +Specify the number of disk sectors per cluster. +Must be a power of 2, i.e. 1, 2, 4, 8, ... 128. +.IP "\fB\-S\fR \fILOGICAL-SECTOR-SIZE\fR" 4 +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. +Values larger than 4096 are not conforming to the FAT file system specification +and may not work everywhere. +.IP "\fB\-v\fR" 4 +Verbose execution. +.IP "\fB\-\-invariant\fR" 4 +Use constants for normally randomly generated or time based data such as +volume ID and creation time. +Multiple runs of \fBmkfs.fat\fR on the same device create identical results +with this option. +Its main purpose is testing \fBmkfs.fat\fR. +.IP "\fB\-\-help\fR" 4 +Display option summary and exit. +.\" ---------------------------------------------------------------------------- +.SH BUGS +\fBmkfs.fat\fR can not create boot-able filesystems. +This isn't as easy as you might think at first glance for various reasons and +has been discussed a lot already. +\fBmkfs.fat\fR simply will not support it ;) +.\" ---------------------------------------------------------------------------- +.SH SEE ALSO +\fBfatlabel\fR(8) +.br +\fBfsck.fat\fR(8) +.\" ---------------------------------------------------------------------------- +.SH HOMEPAGE +The home for the \fBdosfstools\fR project is its +.UR https://github.com/dosfstools/dosfstools +GitHub project page +.UE . +.\" ---------------------------------------------------------------------------- +.SH AUTHORS +\fBdosfstools\fR were written by +.MT werner.almesberger@\:lrc.di.epfl.ch +Werner Almesberger +.ME , +.MT Roman.Hodek@\:informatik.\:uni-erlangen.de +Roman Hodek +.ME , +and others. +The current maintainer is +.MT aeb@\:debian.org +Andreas Bombe +.ME . diff --git a/src/Makefile.am b/src/Makefile.am new file mode 100644 index 0000000..3d22ba7 --- /dev/null +++ b/src/Makefile.am @@ -0,0 +1,63 @@ +# dosfstools src/Makefile.am +# Copyright (C) 2015 Andreas Bombe +# +# This program is free software: you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation, either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY;
