Command line

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.

Options

-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.

History

The fsck_msdosfs utility first appesared in FreeBSD 4.4.

Bugs

The fsck_msdosfs utility is currently under development.
