Those certainly look like hardware failures to me. Before replacing the drive, though, there are a couple of things you can try. One, the drive's SATA cable might be defective. Try replacing it with a known good one. Two, the computer's SATA controller might have gone bad. Try using a different port. If neither of those work, I would guess that the drive itself has gone bad. Hope this helps. --Dale -- Daniel: "This tastes like chicken." Sam: "So what's the matter with it?"
