My 32 GB iPod Touch reports that it has 28 GB filled with music (none of which shows up in the music app) and 22GB OVER capacity with Other. When I uncheck 'Sync music', the music bar drops to zero and the 'other' then jumps to fill up the whole screen and still report 1.8 GB OVER capacity. Clearly something is amiss here and it's not album artwork, email, system files or something like that. Something is corrupted in the file structure, right? I've tried restoring, but did not help. Do I have to reset everything and start from scratch or is there something else i can try?
