Yesterday I sold my 32 gb iPod touch on craigslist and the buyer emailed me today and claims that part of the flash memory is unusable and only 21 gb of music will go on it. I believe when I had it theres was about 27 gb of music, videos and apps on it but I could be wrong. I understand after formatting and installing iOS it's down to more like 30 gb of free space. I had upgraded this to iOS 5. Is there any way that only part of the flash memory would be usable? I couldn't find any threads here talking about it or via a google search.
