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

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

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

DESCRIPTION
     The fsck_msdosfs utility verifies and repairs FAT file systems (more
     commonly 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,
     indicates 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
             foreground, 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      This option is ignored by fsck_msdosfs, and is present only for
             compatibility with programs that check other file system types
             for consistency, such as fsck_ffs(8).

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

     -p      Preen the specified file systems.

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