2015\-04\-16 "dosfstools 4.1" +.SH NAME +\fBfsck.fat\fR \- check and repair MS\-DOS filesystems +.\" ---------------------------------------------------------------------------- +.SH SYNOPSIS +\fBfsck.fat\fR [\fIOPTIONS\fR] \fIDEVICE\fR +.\" ---------------------------------------------------------------------------- +.SH DESCRIPTION +\fBfsck.fat\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 \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. +.\" ---------------------------------------------------------------------------- +.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 \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). +.IP "\fB-b\fR" 4 +Make read-only boot sector check. +.IP "\fB-c\fR \fIPAGE\fR" 4 +Use DOS codepage \fIPAGE\fR to decode short file names. +By default codepage 437 is used. +.IP "\fB\-d\fR \fIPATH\fR" 4 +Delete the specified file. +If more than one file with that name exist, the first one is deleted. +This option can be given more than once. +.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\-p\fR" 4 +Same as \fB\-a\fR, for compatibility with other *fsck. +.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. +This is the default mode and the option is only retained for backwards +compatibility. +.IP "\fB\-t\fR" 4 +Mark unreadable clusters as bad. +.IP "\fB\-u\fR \fIPATH\fR" 4 +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. +This option can be given more than once. +.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. +.\" ---------------------------------------------------------------------------- +.SH "EXIT STATUS" +.IP "0" 4 +No recoverable errors have been detected. +.IP "1" 4 +Recoverable errors
