When I set up my Mac Pro I created an alternate, internal drive that could also be used as a startup drive. I realize that I forget some of the keyboard commands for diagnostic startups, and recognize the inability to research them in crisis when a computer fails to work correctly.

I also consider this as I ponder whether to create an alternate drive so I can try Mountain Lion and at the same time keep a drive with Snow Leopard in case I want to go back.

Thoughts?
