New Hitachi internal drive will not mount

I just bought a 3TB Hitachi UltraStar to install in my Mac Pro. After installation it does not show up on the desk top or in the Disk Utility. I tried it in different drive slots, and also inserted other drives into the slots to make sure all the slots were OK, which they are.


When I take the drive out of the slot it's warm, so it appears to be getting power.


Does anyone have any suggestions on how to mount this drive?


(I tried contacting MacMall where I bought it, but it's Sunday, so no tech support.)


Any help would be greatly appreciated!

Mac Pro, Mac OS X (10.7.5)

Showing on the desktop would actually be bad as it would mean it was pre-formatted for Mac or even as NTFS.


And no need to swap around and try different slots and drives if Disk Utilty won't.


Sometimes if you have Windows installed you could then use Hitachi disk utility and recertify the drive or diagnose it better. WD Lifeguard also.


Packing, box and how it was shipped use to and can be a killer for hard drives if not done right.
