Having spent days getting my library onto the mac, I thought all was well. The iPod synched ok, no probs. Then I thought I would try to use the Notes function on the iPod. I created a few test .txt files and put them on the pod after enabling it as a hard drive. ~Then... None of the music is there anymore! And when I try to sync, no way Hose. Any ideas what I've messed up? I've set the ipod back to not being an external drive.
