+.TH DOSFSCK 8 "2010\-01\-31" "3.0.9" "check and repair MS\-DOS filesystems"
+
+.SH NAME
+\fBdosfsck\fR \- check and repair MS\-DOS filesystems
+
+.SH SYNOPSIS
+\fBdosfsck\fR|\fBfsck.msdos\fR|\fBfsck.vfat\fR [\-aAflnrtvVwy] [\-d \fIPATH\fR \-d\ \fI...\fR] [\-u\ \fIPATH\fR \-u \fI...\fR] \fIDEVICE\fR
+
+.SH DESCRIPTION
+\fBdosfsck\fR verifies the consistency of MS\-DOS filesystems and optionally tries to repair them.
+.PP
+The following filesystem problems can be corrected (in this order):
+.IP "*" 4
+FAT contains invalid cluster numbers. Cluster is changed to EOF.
+.IP "*" 4
+File's cluster chain contains a loop. The loop is broken.
+.IP "*" 4
+Bad clusters (read errors). The clusters are marked bad and they are removed from files owning them. This check is optional.
+.IP "*" 4
+Directories with a large number of bad entries (probably corrupt). The directory can be deleted.
+.IP "*" 4
+Files . and .. are non\-directories. They can be deleted or renamed.
+.IP "*" 4
+Directories . and .. in root directory. They are deleted.
+.IP "*" 4
+Bad filenames. They can be renamed.
+.IP "*" 4
+Duplicate directory entries. They can be deleted or renamed.
+.IP "*" 4
+Directories with non\-zero size field. Size is set to zero.
+.IP "*" 4
+Directory . does not point to parent directory. The start pointer is adjusted.
+.IP "*" 4
+Directory .. does not point to parent of parent directory. The start pointer is adjusted.
+.IP "*" 4
+Start cluster number of a file is invalid. The file is truncated.
+.IP "*" 4
+File contains bad or free clusters. The file is truncated.
+.IP "*" 4
+File's cluster chain is longer than indicated by the size fields. The file is truncated.
+.IP "*" 4
+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.
+.IP "*" 4
+File's cluster chain is shorter than indicated by the size fields. The file is truncated.
+.IP "*" 4
+Clusters are marked as used but are not owned by a file. They are marked as free.
+.PP
+Additionally, the following problems are detected, but not repaired:
+.IP "*" 4
+Invalid parameters in boot sector.
+.IP "*" 4
+Absence of . and .. entries in non\-root directories
+.PP
+When \fBdosfsck\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.
+
+.SH OPTIONS
+.IP "\fB\-a\fR" 4
+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.
+.IP "\fB\-A\fR" 4
+Use Atari variation of the MS\-DOS filesystem. This is default if \fBdosfsck\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).
+.IP "\fB\-d\fR" 4
+Delete the specified file. If more that one file with that name exists, the first one is deleted.
+.IP "\fB\-f\fR" 4
+Salvage unused cluster chains to files. By default, unused clusters are added to the free disk space except in auto mode (\fB\-a\fR).
+.IP "\fB\-l\fR" 4
+List path names of files being processed.
+.IP "\fB\-n\fR" 4
+No\-operation mode: non\-interactively check for errors, but don't write
+anything to the filesystem.
+.IP "\fB\-r\fR" 4
+Interactively repair the filesystem. The user is asked for advice whenever
+there is more than one approach to fix an inconsistency.
+.IP "\fB\-t\fR" 4
+Mark unreadable clusters as bad.
+.IP "\fB\-u\fR" 4
+Try to undelete the specified file. \fBdosfsck\fR tries to allocate a chain of contiguous unallocated clusters beginning with the start cluster of the undeleted file.
+.IP "\fB\-v\fR" 4
+Verbose mode. Generates slightly more output.
+.IP "\fB\-V\fR" 4
+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.
+.IP "\fB\-w\fR" 4
+Write changes to disk immediately.
+.IP "\fB\-y\fR" 4
+Same as \fB\-a\fR (automatically repair filesystem) for compatibility with other fsck tools.
+.PP
+\fBNote:\fR If \fB\-a\fR and \fB\-r\fR are absent, the filesystem is only checked, but not repaired.
+
+.SH "EXIT STATUS"
+.IP "0" 4
+No recoverable errors have been detected.
+.IP "1" 4
+Recoverable errors have been detected or \fBdosfsck\fR has discovered an internal inconsistency.
+.IP "2" 4
+Usage error. \fBdosfsck\fR did not access the filesystem.
+
+.SH FILES
+.IP "fsck0000.rec, fsck0001.rec, ..." 4
+When recovering from a corrupted filesystem, \fBdosfsck\fR dumps recovered data into files named 'fsckNNNN.rec' in the top level directory of the filesystem.
+
+.SH BUGS
+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.

+.SH DESCRIPTION
+.B mkdosfs
+is used to create an MS-DOS file system under Linux on a device (usually
+a disk partition).
+.I device
+is the special file corresponding to the device (e.g /dev/hdXX).
+.I block-count
+is the number of blocks on the device. If omitted,
+.B mkdosfs
+automatically determines the file system size.
+.SH OPTIONS
+.TP
+.B \-a
+Normally, for any filesystem except very small ones, \fBmkdosfs\fP
+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.
+.TP
+.B \-A
+Use Atari variation of the MS-DOS file system. This is default if
+\fBmkdosfs\fP 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, \fBmkdosfs\fP 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 file systems are managed by raising the logical sector size.
+Under Atari format, an Atari-compatible serial number for the
+file system is generated, and a 12 bit FAT is used only for file systems
+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\fP
+option. Some PC-specific boot sector fields aren't written, and a boot
+message (option \fB\-m\fP) is ignored.
+.TP
+.BI \-b " sector-of-backup "
+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.
+.TP
+.B \-c
+Check the device for bad blocks before creating the file system.
+.TP
+.B \-C
+Create the file given as \fIdevice\fP on the command line, and write
+the to-be-created file system to it. This can be used to create the
+new file system in a file instead of on a real device, and to avoid
+using \fBdd\fP in advance to create a file of appropriate size. With
+this option, the \fIblock-count\fP must be given, because otherwise
+the intended size of the file system 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.
+.TP
+.BI \-f " number-of-FATs"
+Specify the number of file allocation tables in the file system. The
+default is 2. Currently the Linux MS-DOS file system does not support
+more than 2 FATs.
+.TP
+.BI \-F " FAT-size"
+Specifies the type of file allocation tables used (12, 16 or 32 bit).
+If nothing is specified, \fBmkdosfs\fR will automatically select
+between 12, 16 and 32 bit, whatever fits better for the file system size.
+.TP
+.BI \-h " number-of-hidden-sectors "
+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. Assumes
+\'0\' if no value is given on the command line.
+.TP
+.I \-i " volume-id"
+Sets the volume ID of the newly created file system;
+.I volume-id
+is a 32-bit hexadecimal number (for example, 2e24ec82). The default
+is a number which depends on the file system creation time.
+.TP
+.B \-I
+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.
+.B mkdosfs
+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 file system can go directly to the whole disk. Under other OSes
+this is known as the 'superfloppy' format.
+
+This switch will force
+.B mkdosfs
+to work properly.
+.TP
+.BI \-l " filename"
+Read the bad blocks list from
+.IR filename .
+.TP
+.BI \-m " message-file"
+Sets the message the user receives on attempts to boot this file system
+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.
+.TP
+.BI \-n " volume-name"
+Sets the volume name (label) of the file system. The volume name can
+be up to 11 characters long. The default is no label.
+.TP
+.BI \-r " root-dir-entries"
+Select the number of entries available in the root directory. The
+default is 112 or 224 for floppies and 512 for hard disks.
+.TP
+.BI \-R " number-of-reserved-sectors "
+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).
+.TP
+.BI \-s " sectors-per-cluster"
+Specify the number of disk sectors per cluster. Must be a power of 2,
+i.e. 1, 2, 4, 8, ... 128.
+.TP
+.BI \-S " logical-sector-size"
+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.
+.TP
+.B \-v
+Verbose execution.
+.SH BUGS
+.B mkdosfs
+can not create boot-able file systems. This isn't as easy as you might
+think at first glance for various reasons and has been discussed a lot
+already.
+.B mkdosfs
+simply will not support it ;)
