Hope this is the right forum for this question. There is a (good) chance that the computer I buy next week will have only one optical drive, so I will have to copy cds to the hard drive before burning them. Does doing this a lot fragment the hard drive? On my old school iMac, I have a firewire burner, so I don't have to deal with this. How long will it take to copy a cd to the hard drive on a 1Ghz G4? If I get a superdrive, can I copy DVD's? Or is the superdrive just for burning projects from imovie and final cut? If I can copy DVD's, how long does it take? Thank you in advance for your help.
