ok, so my internal powerbook hardrive is full, partially due to my iTunes library. Now I have a 180gb laCie hard drive, and I heard it is possible to move my iTunes library to that instead and run off of that. 1: How do I go about moving this correctly and safely, so I do not loose any of my songs? 2: Will my iPod still sync correctly to this when I plug it in? thanks for your help.
