### NAME

fsck_msdos - DOS/Windows (FAT) filesystem consistency checker

### SYNOPSIS

fsck_msdos -p [-f] filesystem ... fsck_msdos [-fny] 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 serious 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 , 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.

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