So, when I plugged in my iPod this morning to update the songs, nothing happened. Normally, iTunes would open and it would begin updating, but this time nothing happened at all. I opened iTunes manually, and lo and behold, there was no "iPod" playlist on the side, implying that it wasn't even recognized. In the preferences it also said no iPod was connected. But when I went to My Computer, I could see it and access the hard disk. Do I have to reformat the iPod and reinstall the software, or is there an easier solution?
