ITunes wiped my entire IPod after moving all the files to a new computer. Freezes ITunes when connected, lags the computer all the way down trying to go into the device from Windows.
Same thing happened to me Bogie. Kept getting error messages. Come to find out, my faithful classic 160GB iPod had died a slow 10 year old death. This was several years ago and I ran straight over and got a new one. I needed something to handle ginormous amounts of music and nothing else.
