According to one aspect and example, a method is provided for handling
write protected storage devices. The method includes generating a read
signal from a portion of a magnetic storage medium and determining if a
modulation pattern is present in the read signal, the modulation pattern
associated with an identification mark comprising a pattern of indicia
associated with a recording layer of the magnetic storage medium. The
identification mark indicates that the storage medium is a write
protected storage device (e.g., a write-once-read-many "WORM" storage
device or the like). If the storage medium is write protected, a media
drive is restricted from write operations to the storage medium according
to the particular write protected scheme, e.g., WORM, write append only,
or the like.
