I have been trying to get a second optical drive in my MDD Mac to work, but I've had problems you may be able to help me with. One drive is the original DVD Rom/CD RW and the other is a superdrive out of my Quicksilver. Firstly setting them up as master and slave properly and putting them on the same ATA33 (original) bus only shows one drive. Putting them on seperate bus as master shows both drives but I can't eject/open one of them (yes I know the Option Eject ect). If you have this or sommeler setup I'd love to hear from you.
