So I have a perfectly functioning 2006 macbook that I want to give my daughter who is going away to school in two weeks. Only problem (I thought) was that the hard drive was only 60gb. So I backed it up, bought a new scorpio with some more gigs and swapped them out. Was surprisingly easy. I have the original system discs, and when I went to boot from the system discs I found out the optical drive is non-functioning. I put the old hard drive back and tried other discs, it just spits them out. It is going to cost a ridiculous amount of money to replace the optical drive, so what I want to know, is can I buy an external cd drive and boot with the system discs from that? Thanks in advance!
