I have an iPod Nano that is formatted to work with my Mac, running OSX. I was traveling and wanted to recharge the Nano but used my PC to do this. It appears that the Nano charged ok (at least from what I can tell) but all of my files have been erased or at least appear to have been erased. Is it possible that when I plugged the Nano into the PC that the Nano got confused by a different OS and erased everything? If so, will I need to 'restore' the Nano then reload what I had on there originally? Or do something else. Feedback is greatly appreciated. Thanks!
