In a word, SOL. Or is that three words. In any case, the drive is locked. You need the password to unlock the firmware in the drive. A grub error indicates the drive was used before. Return it and get your money back or RMA the drive to the manufacturer.
doubt i can return it or rma it its at least 2 years old or so. Idk how long the warranty is on the drive or anything so idk what im gonna do. Could i use parted magic boot disk and go into linux an use HDparm to unlock the drive?
