I had something similar happen to me. My little girl's nano was synced to the wife's macbook and when i wanted to start using it on the tower it wouldn't work. For whatever reason. So I since I had all the info from the ipod on one or the other computer, I just erased the ipod (in disk utility) and reformatted in itunes (on the tower). Its worked like a champ ever since.
