Situation: I have a 2007 Macbook Pro. The Superdrive no longer will read cd's or dvd's. I just purchased a new iMac. Now I want to sell my MBP but I need to wipe it clean and reinstall the system software before I put it on Craigslist. How can I do that with a broken Superdrive? I am thinking maybe I can connect it to my iMac via firewire and boot the MBP in target disk mode. But then what? How do I wipe it and reinstall mac osx? Thanks in advance.
