I have a 3rd generation ipod http://www.everymac.com/systems/apple/consumer_electronics/stats/ipod_3rdgen.html My ipod used to connect to my computer with my firewire cable. Now when I plug it in, it charges but does not show up in itunes or the desktop. Other ipods connect using this same cable, and my ipod can connect to my computer using my friend's 4th gen. USB cable. Therefore, this doesn't seem to be any of the following: 1) firewire port problem 2) cable problem 3) ipod hard drive problem I have NO IDEA what it could be, since my ipod is updated to version 2.3 and my itunes and operating system are all the most recent. Please help if you can!
