Im looking at getting a new CD-R or CD-RW drive since my old one will no longer work with my comp. Im looking at some from OWC becasue they come with Toast 4.1 and are only about 300 dollars. 1 model is firewire which is what i really want, but is most expensive. Second is an internal IDE, ok now im going to sound like an idiot here, btu what is IDE? ive got a 400mhz G4, non-sawtooth.
