I have a new Hitachi Deskstar SATA drive that I'd like to install as a secondary drive. When I install it, the Hitachi drive is recognized, but my original drive is not showing in the bios. If I turn the computer off and unhook the Hitachi, it boots right up recognizing the original drive. It's been years since I did much hardware work on computers, and I know some things have changed. Is there a jumper switch I need to fix to make the Hitachi a slave? (Book that came with it was totally useless.) Why doesn't the original drive show in the bios when the Hitachi is hooked in? I'm more a software person than hardware but I didn't think installing a secondary internal drive would be that tough. Ideas?
