I'm a new itunes user so please bear with me. When Apple released itunes 4, I decided it was finally time to try it out. So for the past two weeks I've been steadily feeding my CD collection into my G4. So far it's really, really cool. Now I don't have to worry about scratching, distintigrating, losing CDs, etc. But now I'm up to the letter E into my collection (I organize alphabetically) and already have 13 gigs with AAC. I know that I never want to rip this many CDs again and would love to put my CDs into storage. So I have the following questions: 1. Can I just move my itunes library folder to my second internal HD to make a backup of it? 2. If I were to get a Powerbook, can I just copy the itunes folder to it to have all the files? 3. I bought a couple dozen songs from the Apple Music Store. Will these act any different if I do either of the above? 4. My Superdrive is now acting a bit flaky. It makes a much louder noise when ripping CDs and will startup and stop multiple times while ripping a single CD. Has this occured to anyone else? Any suggestions on how to fix it? Man, I really should have done this while it was still under warranty! Thanks!
