The CD-ROM/DVD-ROM drive in my G3 PB quit working. No idea why, but it's been about a year now and I'm struggling with whether to replace it. What happens to these things? Do they just die, or is there somewhere in OS X I can go to get this thing working? Pls advise. I've had the machine for 5 good years now, and this is the only thing wrong with it now. BTW -- It's running 10.2.8 and has never run better. Except for the CD-ROM... Thanks!
