MY 40 gb seagate was pronounced dead by seagate's HDD utilities (I downloaded it with my other machine). I COULD NOT RESTORE with FACTORY RESCUE DISK or any other disk or even with a copy of retail Windows. I used DD10 in stand alone mode to "wipe" the HDD and it did! I then was able to restore my compaq presario with the factory restore disks and the hard disk is working fine. It does clatter a bit but otherwize works good. I think "wiping" the hard disk let the restore disk to "slide" onto the disk since it was now raw.
