My 4G 20 gig ipod is not working after two years of solid abuse. During file transfers my ipod hard drive turns on and off over and over and eventually locks up my comptuer until I disconnect the ipod. I have tried closing the ipod software then connecting the ipod, then re-opening ipod software, but alas, the same problem occurs. Honestly, I am fine with it because it gives me an excuse to upgrade to hi-mid. I use the word upgrade because I really do like mini-discs better than hard drive or flash based mp3 players. But I would like to get my ipod to work if I don't have to pay money to fix it, hehe. anyway... peace, Donald
