Same thing happened to a buddy today, except only one drive disappeared. I brought over my XP Pro disk (his was an upgrade) and loaded it, and it found the second drive! Also, when I pulled the disk out of the case, I found my W2K AS disk that I have been looking for. Tomorrow, I will work on my server.

I am optomistic now. Might be common to the motherboard that we share. I'm glad there wasn't anything on the little C: drive. I might even format it first.
