Hi, I'm trying to switch my ipod nano from a PC format to a mac format, but i'm hitting problems. (The format change will be perminant) It works fine on the PC and 'disk use' is enabled and works. When plugged into my mac (OS 10.3.9) it fails to be picked up. The system profiler CAN see it and says its windows formated but itunes, desktop and ipod updater fail to find it. I've done a successful reset by holding the menu and middle button but to no avail. so how the hell do i reformat it if my mac can see it???!!!! does the PC have to reformat it? thanks if you have any suggestions? Jo.
