Ok, here's the story. My computer was really filthy, so I thought of cleaning up. Took out the delicate parts (the 2 HDDs and graphics card), cleant the motherboard, processor heatsink, etc. After everything was done, I put everything back. The 80GB shows at the startup IDE detection. But... it just dosen't boot from it, instead the computer boots from my 120GB SATA. The 80GBs drives don't show in windows. But it's detected in device manager. Partition magic crashes in windows and dosent start at all in DOS. I don't care as much for the hard drive as for the data on it. HELP!
