Heres the story... I was running a 80gb 10k w/ my OS and a 250gb for storage. Everything worked beautifully until I re-installed my OS. When I re-installed I had my 250gb unplugged. When I came to a fresh desktop I shut down and plugged up my 250gb, but the PC would not boot to my desktop with the 250gb plugged in. It would boot to my BIOS, and it would see the drive, but would not boot to desktop. While playing with it I made the mistake of trying to plug up the 250gb with the PC still on. I didn't plug in the power, only the SATA cable to my MOBO. But as soon as I did the whole PC shut down completely. When I turned it back on the PC would not see my 10k. So now I have a 10k that the PC won't see, and a 250gb that the PC won't boot with. What am I to do? Thank you.
