I have a Itouch 2nd gen 16G When I try to download in Itunes I get a message that says Ipod cannot not be synced. The disk could not be read from or written to. I can download into my touch thru the wifi but can't do anything in Itunes. I have Itunes 220.127.116.11. and my ipod software is up to date. I'm working with windows XP. Any help would be appreciated.
