When I see my iPod management screen in iTunes, the "enable disk use" box is checked, but the check box is grayed out so that I can't uncheck it. How do I turn off disk mode? So I have to trash every file and folder on it through the finder first? In the finder it shows no files on the iPod except for the ones it created automatically. It shows the empty folders it automatically created, the calendar.ics files that it auto created when I once turned on the Sync Calendars option in iTunes (which is now turned off), and the instructions file it auto created in the Notes folder. Should I select all and trash them in order to turn disk mode off?
