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

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

SYNOPSIS
     fsck_msdos -q special ...
     fsck_msdos -p [-f] special ...
     fsck_msdos [-fny] special ...

DESCRIPTION
     The fsck_msdos utility verifies and repairs FAT file systems (more com-
     monly known as DOS file systems).

     The first form of fsck_msdos quickly checks the specified file systems to
     determine whether they were cleanly unmounted.

     The second form of fsck_msdos preens the specified file systems.  It is
     normally started by fsck(8) run from /etc/rc.boot 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 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 confirma-
     tion 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 sys-
                   tem types for consistency.

           -n      Causes fsck_msdos to assume no as the answer to all opera-
                   tor questions, except ``CONTINUE?''.

           -p      Preen the specified file systems.

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

EXIT VALUES
     fsck_msdos exits with a value of 0 when the filesystem is clean (or has
     been repaired), and 8 otherwise.

     fsck_msdos is still under construction.
