I've got a 3 year old iPod Classic 160g. Went to use it the other day and noticed that everything had been wiped off it and it had gone back to factory settings. Tried to re-sync it. I kept an eye on the sync (over 17,000 songs) and it seemed like it was working fine but when it completed, there was still nothing on the iPod. Anyone had this problem and know a way of remedying it? Thanks!
