As a Christmas present to my grandparents I was going to backup their data, format their hard drive and reinstall the OS so their computer ran better. A few minutes after started to work on it the logic board on the outside of the hard drive bit the dust (picture). It looks replaceable if I can just find another logic board that will fit on the drive. The drive is question is a Seagate Barracuda 7200.9, 320 GB 3.5" SATA drive (model # ST3320833AS). Does anyone have this exact drive that they would want to sell? Or know of a place where I could get this drive or Seagate replacement parts? Please, I need to get this drive back up and working because I didn't get a chance to back up any of their data. They'd be crushed if I lost it.
