You are way beyond my technical knowledge on this one... but I think I may have a couple more "uh-ohs" to think about.
You'll have to find a way to power the CD-ROM. What's it looking for? 3V DC? 5v DC? Whatever it is, your car probably isn't going to supply it... Oh, I see - you want to power it from the empeg. Hmmm....
Worse, I suspect the service life of the actual physical unit is going to be disappointingly brief. That unit was never designed to be bumped and banged around while it is operating. If it is made for laptop use, it'll take quite a bit of abuse when it is not spun up, but while it is in use, I'll bet it is fairly delicate. By contrast the hard drives in the empeg are designed to take 150g impacts while spinning!
But it sounds like a really great idea if you can make it fly. Please keep us posted on any progress you make. Verement, Raphael, Borgcube, etc. -- what do you guys think?
