It has 8 bytes extra per block compared to the standard 512 bytes/block. It will need a low level format to make it 512. In most cases that is done via a mode select command, followed by a format unit command. Check with IBM how this is done for their drives, as this kind of stuff is vendor unique. -- Wilko Bulte wilko@FreeBSD.org
