NAME

fsck_msdos, fsck_dos- create an MS-DOS (FAT) file system

SYNOPSIS

fsck_msdos [-p]
fsck_msdos [-n| -y] [-v]

DESCRIPTION

fsck_msdos is a target utility.

This utility checks and repairs FAT filesystems (more commonly known as DOS filesystems).

The first form of fsck_msdos preens the specified filesystems. It is usually started at boot time (see rc.classix ) during automatic reboot.

When preening file systems, fsck_msdos repairs common inconsistencies non-interactively. If more serious problems are found, fsck_msdos does not try to repair them, indicates that it was unsuccessful, 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 following options are provided:

-n

Causes fsck_msdos to use no as the answer to all operator questions, except CONTINUE? .

-p

Preens the specified filesystems.

-y

Causes fsck_msdos to use yes as the answer to all operator questions.

-v

Causes fsck_msdos to display information about the boot sector. (Mainly used for debugging purposes.)

DIAGNOSTICS

1. Boot block was modified.

2. One or more directories were modified.

3. The FAT was modified.
