According to one aspect of the invention, methods and systems for
operating a magnetic storage media drive to perform read/write operations
to magnetic storage media in an overwrite protected mode are provided. In
one example, a method includes receiving a write request and associated
write data and determining if the magnetic storage medium is overwrite
protected. If the storage medium is overwrite protected the method
includes writing the write data to the storage medium followed by an EOD
marker associated with the end of the write data, allowing write
operations to the storage medium after previously written data, and
preventing write operations to the storage medium prior to previous EOD
markers.
