There are commercially available programs that guarantees to wipe your drive clean - including hidden areas and remapped sectors. You should then be able to send drives back for warranty replacement. There are also bulk erasers that reset every bit magnetically, but those will probably void the warranty too. (You'll need a low-level reformat to recreate sector addresses on the suddenly blank surface.) Helge Hafting
