I'm having the EXACT same problem. When unplug the iPod, it seems to be normal again.
bumping because it's really pissing me off and I'd like help.
I have been using my ipod for about 6 months now and love it. Then all of a sudden I encounter this major problem. One day I plugged in my ipod to sync and the message "need to restore ipod" or something similar came up, so I did but now whenever I plug in my ipod my itunes freezes, and goes to 'not responding' and the rest of my computer either freezes or slows down to unusable. Someone please help me. Thanks in advance.
