FSCK_MSDOS(8)

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

SYNOPSIS
-q filesystem ...
-p [-f] filesystem ...
[-fny] filesystem ...

DESCRIPTION

The fsck_msdos utility verifies and repairs FAT filesystems (more commonly known as DOS filesystems).

The first form of fsck_msdos quickly checks the specified filesystems to determine whether they were cleanly unmounted. This option is used by autodiskmount(8) to determine whether to perform a full check before mounting a volume.

The second 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, 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, such as fsck_ffs(8).

-n  Causes fsck_msdos to assume no as the answer to all operator questions, except “CONTINUE?”.

-p  Preen the specified filesystems.

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