Okay, so here I was, going to update my iPod. I plugged it in, opened up iTunes and waited a couple of seconds for the computer to detect the iPod. Usually my iMac will just detect it after a few seconds and update it real fast. Well, the computer never detected my iPod, so I thought I would just unplug it and then plug it back in - mistake. My iPod just stayed at the "Do Not Disconnect" screen. I can't get it off the "Do Not Disconnect" screen. I tried to turn it off, but it wont. Can someone tell me how to fix it?!
