I had to run to campus a couple days ago to print something off so I grabbed my shuffle, set up a playlist, and copied my files that needed to be printed. Ran to campus, printed, ejected the shuffle and took off. When I went to play music on it I got the flashing error lights. Now my PB at home won't recognize it in iTunes, Finder, Disk Utility, /volumes, etc. Do I have to bite the bullet here and take it in to be fixed? Or is there something else I can try?
