FSCK_MSDOS(8) BSD System Manager's Manual FSCK_MSDOS(8) NAME
fsck_msdos -- DOS/Windows (FAT) filesystem consistency checker SYNOPSIS
fsck_msdos -p [-f] filesystem ... fsck_msdos [-fny] [-x snap-backup] filesystem ... DESCRIPTION
The fsck_msdos utility verifies and repairs FAT filesystems (more commonly known as DOS filesystems). The first form of fsck_msdos preens the specified filesystems. It is normally started by fsck(8) run from /etc/rc during automatic reboot, when a FAT filesystem is detected. When preening file systems, fsck_msdos will fix common inconsistencies non-interactively. If more seri- ous problems are found, fsck_msdos does not try to fix them, indicates that it was not successful, and exits. The second form of fsck_msdos checks the specified file systems and tries to repair all detected inconsistencies, requesting confirmation before making any changes. 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 Causes fsck_msdos to assume no as the answer to all operator questions, except ``CONTINUE?''. -p Preen the specified filesystems. -x snap-backup Use a snapshot with snap-backup as backup to check a read-write mounted filesystem. Must be used with -n. See fss(4) for more details. The point is to check an internally-consistent version of the filesystem to find out if it is damaged; on failure one should unmount the filesystem and repair it. -y Causes fsck_msdos to assume yes as the answer to all operator questions.

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 commonly 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, indicates 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 confirmation 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 system types for consistency. -n Causes fsck_msdos to assume no as the answer to all operator questions, except ``CONTINUE?''. -p Preen the specified file systems. -y Causes fsck_msdos to assume yes as the answer to all operator questions.
