Hey everyone, I just got a Western Digital Caviar Black series 500 GB SATA II Hard drive, and put it into my computer as a slave drive. I have the RC and all drivers are installed correctly. The drive shows up in the bios, and in device manager, but when I go to computer, it does not show up. Another interesting fact is that when I stuck it into a different computer, when I tried to install Windows (XP and 7 RC) both installations failed to find the hard drive... I'm confused! Any suggestions?
