Ok, so I've got a Philips DVD R/RW drive and I want to put it in my Mac Pro. I put it in, hooked everything up, but it won't open for me (opt. + Eject, I know). It's set on cable select, but I've also tried it on slave with the stock on master. Anyone have any ideas? I'd like to get this working as soon as I can. PS, when I wake the MP from sleep, the light on the second drive blinks, but nothing else. PPS, the first optical drive opens with opt. + eject regardless.
