Does the computer that had this drive in it boot up at all with the drive in it? I mean like POST and gt as far as identifying the drives?
You could hook the drive up as slave to any other HDD in your system. If in doing so the computer refuses to boot then remove the drive and try booting again. If it works I would say the drive is dead. If it boots with the "dead" drive in it, is it accessable as a slave drive? If so you may just need to repartition and reformat the drive. If not then you probably do have a bad drive.
