I'm still saving for my Mac Pro.... I just bought a green Ipod nano..oh its so beautiful! ! I have a black 60 gb as well.... Anyway I plugged it into my Vista machine and it just said "Do not disconnect" for the better part of 5 minutes...Anyhow i was very upset... I then discconected my iPod adn all the songs were gone..... i had maybe 40 gigs of music on there... Could it mess up my new iPod nano? Any advice..feedback input? Thanks....
