And so the saga continues.

The 40 gig returned an ok result after a thorough scan. Took the 20 gig out and tried an OS install on it. This time the OS won't even install. Did everything... took out all peripherals except the video card. Swapped out the CD drive with one that I know works. Damn thing starts installing then screws up. Dammit... I'm gonna flash the BIOS and then I am lost because it means its not a messed up drive its something worse.
