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

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

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

     -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 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.

     The fsck_msdosfs utility appeared in NetBSD 1.2.  fsck_msdosfs first
     appeared in FreeBSD 4.4.

     The fsck_msdosfs utility is currently under development.
