I have an IPOD 60 GB Photo purchased in March, 2005. IPOD has frozen in the past, but latest problem occurred with MAC OS 10.4. The IPOD isn't showing music files, but the space is still being "used" and/or is unavalvable. I have followed instructions to reset, (worked in the past) but it won't reset. nothing happens when I hold down the appropriate keys. Anybody else have this problem or have any ideas? Do you think an Apple store will provide a replacement if they can't get it to reset? Do I neeed to see a genius (by appointment) or can I just bring it to the store for someone to try to reset?
