Hitachi hard drives are notorious for this... so much so they have earned the nickname "Deathstar" (not Deskstar) in the trade. (they go into a lockdown mode and the only way to unlock them is from a WindDUHows app). If you're still under warranty I would be talking to Apple about replacing the dead drive. If you're not I don't know if contacting Hitachi would generate any good news- but it's worth a try.

Your only option is to replace the drive... FWIW I would not get another Hitachi.

Good Luck,
