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

NAME
     fsck_msdos	-- DOS/Windows (FAT) filesystem	consistency checker

SYNOPSIS
     fsck_msdos	-p [-f]	filesystem ...
     fsck_msdos	[-fny] [-x snap-backup]	filesystem ...

DESCRIPTION
     The fsck_msdos utility verifies and repairs FAT filesystems (more com-
     monly known as DOS	filesystems).

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

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

     The options are as	follows:

     -f		       This option is ignored by fsck_msdos, and is present
		       only for	compatibility with programs that check other
		       file system types for consistency, such as fsck_ffs(8).

     -n		       Causes fsck_msdos to assume no as the answer to all op-
		       erator questions, except	"CONTINUE?".

     -p		       Preen the specified filesystems.

     -x	snap-backup    Use a snapshot with snap-backup as backup to check a
		       read-write mounted filesystem.  Must be used with -n.
		       See fss(4) for more details.  The point is to check an
		       internally-consistent version of	the filesystem to find
		       out if it is damaged; on	failure	one should unmount the
		       filesystem and repair it.

     -y		       Causes fsck_msdos to assume yes as the answer to	all
		       operator	questions.
