Today, I left my iPod to charge, but when I got home, the computer was off. I have Vista, so it came back to everything that was previously there. My iTunes had a pop-up saying: "The iPhone could not be recongnized." or something like that... It's an iPod, not an iPhone? Whatever, then when I check my iPod, the day says: December 7th, 2007 - New York Time (which was like 1:43 AM) I've fixed it all, and my music and stuff is all there. Just wonderin' if it's ever happened to you.
