Looks like a drive taken from a RAIDarray of some sorts.  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.
