My second hard drive, the 500 GB monster, has disappeared. It's been installed, according to Windows XP. Heck, when I check the Properties under the main hard drive, if I go to the Hardware tab, it's right there. The Device Manager says it's working properly, just fine. Despite all this, I can't find it anywhere! While Windows XP swears up and down that it's there and functioning properly (even to the point of being able to hit the Populate button and getting a proper readout), I still can't find the dang thing. It just isn't there. It's not even hidden or anything, it's just . . . gone!
What's going on here?
