My friend showed me how to use my ipod as an external HD and I put 12 gig of stuff on it when I cleaned off my back-up drive. Now when I double click on my iPod from my desktop it opens but the data is nowhere to be found. I know it is still there because my iPod is full and there is only 25 gig in my iTunes. Has this happened to any of you? How can I find this folder? As a last resort can I wipe the iPod completly and just reload all my music?
