DOS/Windows (FAT) file system
fsck_msdos utility verifies and
repairs FAT file systems (more commonly known as DOS file systems). It
checks the specified filesystem and tries to repair all detected
inconsistencies, requesting confirmation before making any changes.
-p flag is given,
fsck_msdos preens the specified filesystem. It is
normally started this way by
fsck(8) run from
during automatic reboot, when a FAT file system is detected. When preening
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 options are as follows:
- 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).
- Assume a “no” response to all questions asked by
fsck_msdosexcept for “CONTINUE?”, which is assumed to be affirmative. The filesystem will not be opened for writing. This is the default for file systems to be checked that are concurrently mounted writable.
- Preen the specified filesystem.
fsck_msdosto assume “yes” as the answer to all operator questions.
If neither of the
-n options are specified, the user may force
fsck_msdos to assume an answer of
“yes” to all the remaining questions by replying to a question
with a value of “F”.
