Just bought a LaCie to help me clear some space off my Macbook Pro. I have a few questions. 1) I have 60gb of music on my macbook pro. I moved over an album from my music folder, deleted it from my computer, and played it from my hard drive. it only played the song I chose even though all the songs stayed in my iTunes. Would I have to delete all my music and just choose an album to add to my computer when I wanted to listen to it? 2) How do i find the OTHER files that are displayed in my storage? 3) How many free gb should my computer have to be safe? I average between 20-30gb. I'd like to have 50 free. Thanks.
