Did you have it set to dynamic disk (they suck)
If you re-did the MBR, you should at least see something.
I would say send it to me and have me fix it, you pay shipping both ways. No promises though. And, if they are MP3's, I reserve the right to copy them
FYI, data storage is my profession and I am paid very well. Ask Shaggy and Koko.
