FSCK_MSDOS(8)           OpenBSD System Manager's Manual          FSCK_MSDOS(8)

NAME
     fsck_msdos - DOS/Windows (FAT) file system consistency checker

SYNOPSIS
     fsck_msdos [-fnpy] filesystem ...

DESCRIPTION
     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 automat-
     ic reboot, when a FAT file system is detected.  When preening file sys-
     tems, fsck_msdos will fix common inconsistencies non-interactively.  If
     more serious problems are found, fsck_msdos does not try to fix them, in-
     dicates 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
             writable.

     -p      Preen the specified file systems.

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