My ipod classic 7th generation won't show up in itunes. I have made sure that it is the latest version of itunes, and resetted both the computer and the ipod. I have also made sure to try different USB ports, and I even tried using itunes on a different computer. My computers both detected the ipod and the ipod said it was connected, but it did not show up in my itunes at all until I unplugged it from the computer(at which point the itunes showed a message saying that it detected a corrupt ipod). This is a 160 GB version, and when I look on the ipod, it shows only 59.7 GB free for use, although there is no media on the ipod besides the original games and such. Can you please help me with information on how I can fix this problem?
