NAME
msdos.util – DOS/Windows (FAT) file system utility
SYNOPSIS
msdos.util -m mountflag1 mountflag2 mountflag3 mountflag4 device node
msdos.util -p mountflag1 mountflag2 mountflag3 mountflag4 device

DESCRIPTION
The msdos.util command supports the mounting, probing, and unmounting of FAT file systems.
Options:
- -m mountflag1 mountflag2 mountflag3 mountflag4
-
mount
- -n
-
set name
- -p mountflag1 mountflag2 mountflag3 mountflag4
-
probe for mounting
- -u
-
unmount
- -k
-
print volume UUID
mountflags above are either:
-
removable or fixed
-
readonly or writeable
-
suid or nosuid
-
dev or nodev
FAT volumes do not actually have a volume UUID. They have an optional 4-byte volume ID. If a volume has an ID, then it will be converted to a version 3 UUID using MD5 to checksum the kFSUUIDNamespaceSHA1 UUID folowed by the volume ID.
For the -k option, if the volume has a volume ID, the exit status will be 253 and the UUID will be printed to standard out, without any trailing newline. Otherwise, if the volume appears to be FAT, the exit status will be 255. If the volume does not appear to be FAT, the exit status will be 254.
