fsck_msdosfs(8)

NAME

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

The fsck_msdosfs utility verifies and repairs FAT file sys
tems (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 automat
ic reboot, when a FAT file system is detected. When preening file sys
tems,
fsck_msdosfs will fix common inconsistencies non-interac
tively. 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 immedi; ately in foreground, or if its cleaning can be deferred to back; ground. FAT
(MS-DOS) file systems must always be cleaned in the; foreground.
A non-zero exit code is always returned for this op; tion.
-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 first appeared in FreeBSD 4.4.
