Yes, I do have two optical drives in the Mac. One is a Mac Superdrive, and the other is an LG Blu-ray drive. One of my external hard drives is using Firewire, but no audio or video devices are using it.
I am new to owning a Mac Pro, so I am pretty much lost as to how to solve (or even find) conflicts. Where do I start?
Thanks for your help and sorry I took so long to respond. My work load is heavy and my computer play time is very limited!
