fsck_msdos
—
DOS/Windows (FAT) file system
consistency check
SYNOPSIS
fsck_msdos |
-q special ... |
fsck_msdos |
-p [-f ]
special ... |
fsck_msdos |
[-fny ] special ... |
DESCRIPTION
The fsck_msdos
utility verifies and
repairs FAT file systems (more commonly known as DOS file systems).
The first form of fsck_msdos
quickly
checks the specified file systems to determine whether they were cleanly
unmounted.
The second form of fsck_msdos
preens the
specified file systems. It is normally started by
fsck(8) run
from /etc/rc.boot during automatic reboot, when a
FAT file system 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, indicates that
it was not successful, and exits.
The third form of fsck_msdos
checks the
specified file systems and tries to repair all detected inconsistencies,
requesting confirmation before making any changes. The default behavior is
to always ask for confirmation of each change. Use the -n or -y options to
override this default behavior.
The options are as follows:
-q
- Causes
fsck_msdos
to quickly check whether the volume was unmounted cleanly. If the volume was unmounted cleanly, then the exit status is 0. If the volume was not unmounted cleanly, then the exit status will be non-zero. In either case, a message is printed to standard output describing whether the volume was clean or dirty. -f
- This option is ignored by
fsck_msdos
and is present only for compatibility with programs that check other file system types for consistency. -n
- Causes
fsck_msdos
to assume no as the answer to all operator questions, except “CONTINUE?”. -p
- Preen the specified file systems.
-y
- Causes
fsck_msdos
to assume yes as the answer to all operator questions.
EXIT VALUES
fsck_msdos
exits with a value of 0 when
the filesystem is clean (or has been repaired), and 8 otherwise.

BUGS
fsck_msdos
is still under
construction.
