FSCK_MSDOS(8) BSD System Manager's Manual FSCK_MSDOS(8)
fsck_msdos - DOS/Windows (FAT) file system consistency checker
fsck_msdos [-fpny] filesystem ...
The fsck_msdos utility verifies and repairs FAT file systems (more com-
monly known as DOS file systems). It checks the specified file systems
and tries to repair all detected inconsistencies, requesting confirmation
before making any changes.
If the -p flag is given, fsck_msdos preens the specified file systems. It
is normally started this way by fsck(8) run from rc(8) 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, indi-
cates that it was not successful, and exits.
The options are as follows:
-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 Assume a "no" response to all questions asked by fsck_msdos ex-
cept for "CONTINUE?", which is assumed to be affirmative. File
systems will not be opened for writing. This is the default for
file systems to be checked that are concurrently mounted writ-
able.
-p Preen the specified file systems.
-y Causes fsck_msdos to assume "yes" as the answer to all operator
questions.
fs(5), fstab(5), fsck(8), fsck_ffs(8), mount_msdos(8), newfs_msdos(8),
rc(8)
fsck_msdos is still under construction.
