FSCK_MSDOSFS(8)           BSD System Manager's Manual          FSCK_MSDOSFS(8)

     fsck_msdosfs -- DOS/Windows (FAT) file system consistency checker

     fsck_msdosfs -p [-f] filesystem ...
     fsck_msdosfs [-fny] filesystem ...

     The fsck_msdosfs utility verifies and repairs FAT file systems (more com-
     monly known as DOS file systems).

     The first form of fsck_msdosfs preens the specified file systems.  It is
     normally started by fsck(8) run from /etc/rc during automatic reboot,
     when a FAT file system is detected.  When preening file systems,
     fsck_msdosfs will fix common inconsistencies non-interactively.  If more
     serious problems are found, fsck_msdosfs does not try to fix them, indi-
     cates that it was not successful, and exits.

     The second form of fsck_msdosfs checks the specified file systems and
     tries to repair all detected inconsistencies, requesting confirmation
     before making any changes.

     The options are as follows:

     -F      Compatibility with the wrapper fsck(8) which seeks to determine
             whether the file system needs to be cleaned immediately in fore-
             ground, or if its cleaning can be deferred to background.  FAT
             (MS-DOS) file systems must always be cleaned in the foreground.
             A non-zero exit code is always returned for this option.

     -f      Force fsck_msdosfs to check ``clean'' file systems when preening.

     -n      Causes fsck_msdosfs to assume ``no'' as the answer to all opera-
             tor questions, except ``CONTINUE?''.

     -p      Preen the specified file systems.

     -y      Causes fsck_msdosfs to assume ``yes'' as the answer to all opera-
             tor questions.

     fsck(8), fsck_ffs(8), mount_msdosfs(8)

     The fsck_msdosfs utility is currently under development.

     The fsck_msdosfs utility first appeared in FreeBSD 4.4.
