.Sh NAME
.Nm fsck_msdos
.Nd DOS/Windows (FAT) filesystem consistency checker
.Sh SYNOPSIS
.Nm fsck_msdos
.Fl p
.Op Fl f
.Ar filesystem
.Ar ...
.Nm fsck_msdos
.Op Fl fny
.Ar filesystem
.Ar ...
.Sh DESCRIPTION
.Pp
The
.Nm
utility verifies and repairs
.Tn FAT
filesystems (more commonly known as
.Tn DOS
filesystems).
.Pp
The first form of
.Nm
preens the specified filesystems.
It is normally started by
.Xr fsck 8
run from
.Pa /etc/rc
during automatic reboot, when a FAT filesystem is detected.
When preening file systems,
.Nm
will fix common inconsistencies non-interactively. If
more serious problems are found,
.Nm
does not try to fix them, indicates that it was not
successful, and exits.
.Pp
The second form of
.Nm
checks the specified file systems and tries to repair all
detected inconsistencies, requesting confirmation before
making any changes.
.Pp
The options are as follows:
.Bl -hang -offset indent
.It Fl f
This option is ignored by
.Nm fsck_msdos ,
and is present only for compatibility with programs that
check other file system types for consistency, such as
.Xr fsck_ffs 8 .
.It Fl n
Causes
.Nm
to assume no as the answer to all operator
questions, except
.Dq CONTINUE? .
.It Fl p
Preen the specified filesystems.
.It Fl y
Causes
.Nm
to assume yes as the answer to all operator questions.
.El
.Sh SEE ALSO
.Xr fsck 8 ,
.Xr fsck_ffs 8 ,
.Xr mount_msdos 8
.Sh BUGS
.Nm Fsck_msdos
is still under construction.
