I actually had a similar problem, I don't recall the specific error code though... We had an HD prepared on a dif box, then put it in my box. Same bios, same version... etc... For some reason, when we moved the drive back, my box was not happy with the drive jumper settings. His box liked the drive when set on master. And mine would only work with the drive on cable select. I don't know if this is your prob or not, but it's quick, easy, and worth a shot. Just switch the jumper from master --> cable select, or the other way around.
