Hello, The issue I'm experiencing is that I cannot get my nano to stop acting as a removable disk, despite the fact that the option is unchecked in iTunes. Yes, the options to Enable Disk Use is unchecked, and yet every time I plug in my device, it pops up as a removable disk. It's kind of annoying. How did this happen? Well, I turned it on to test it, on my WinXP machine. Then, a friend took the iPod and plugged it into her mac. She didn't sync, but iTunes was running, and I'm not sure what happened. When I plugged it back into the XP machine, I disabled the option, but it would still come up. After trying to enable/disable again, I restored the device. Same problem. Any ideas?
