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.
