FSCK_MSDOSFS(8) BSD System Manager's Manual FSCK_MSDOSFS(8)
NAME
fsck_msdosfs -- DOS/Windows (FAT) file system consistency checker
SYNOPSIS
fsck_msdosfs -p [-Cf] filesystem ...
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.
The options are as follows:
-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.
