Yeah, they all seem to be different in little details like that, although they're all optical drives. That's why I stick with a particular model/unit, so I'm somewhat familiar with it before I crack the thing open and start fiddling with stuff. The real kicker is when the manufacturer changed to a new unit rebadged, but it's still listed as the same model #! I'd love to see what you come up with, Bod; judging by the past work it'll be creative I'm sure. Keep it up, man!
