Hi everyone! My idiot teenage son left his retail disks somewhere two states away in his dorm room. I am upgradings his hard drive from a 40 gig to a 160gig in his ibook. We are visiting family so I don't have acess to my disk either. Can I copy his drive to a dvd, and then copy it over after I install the new hard drive? I've done this before, but never with a dvd or cd. He is running 10.5.8. Thank you in advance!
