NAME

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

SYNOPSIS

     fsck_msdosfs -p [-Cf] filesystem ...
     fsck_msdosfs [-Cny] 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:

     -C      Compatibility with the corresponding fsck(8) option (skip check if clean), defined to no-op.

     -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 operator questions, except ``CONTINUE?''.

     -p      Preen the specified file systems.

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