Well, I have 15 GB of space free of my 120 GB macbook drive (32 of it goes to windows). I am a photographer so I am constantly eating disk space. Do you think that I should just keep my photography on seperate drives (2 gbs of space), or stash my enormus 30 GB Itunes library on 2 different drives, and delete the one I have off my computer??? Would I be risking too much?????
