Hello, I just installed a 500GB SATA 6Gbs Hard Drive in bay 2 of my Early 2008 Mac Pro. When I go to disk utility, I can see that the computer reads the drive, it knows it is there. But it doesn't come up anywhere in my finder. It would be impossible at this point to drop anything into it or to turn it into my back up HD through time machine, which is ultimately what I'd like to do. Any ideas as to why this is happening?

Where did the drive come from?

Is it brand new? Or is it from another computer?

If it's brand new, did you initialize it yet? (Using Disk Utility)
