Ok so its an 80gb iPod classic and im using it with a Macbook Pro and a Mac Pro. And this is whats going on: I plugged it in and itunes says it cant recognize it and that I need to restore it. So I did. And now Im in the process of adding all my music back to it. But now Ive noticed that sometimes on certain songs it freezes and I get the spinning ball for like 3-4 mins, then it just stops without ever playing it, and where the cover art goes (bottom left in itunes) it turns black. Also when I eject it from my comp it always goes back to the screen where it has me select the language. Ive tried doing a hard reset now 4 times and even went in disc utility (on my mac) and ran the verify and repair tests with no errors but it always does the same things. Some songs work and some make the ball thing. I also tried running diagnostic mode (on ipod) but when it came to the "FW" test I had to stop because I dont have FW ipod cable. Im really close to giving up on this thing. Please help!!
