I also have a 3tb WDC Green HDD attached. When I go into the Bios, I can see the drive under ATA Devices. It lists its serial name (WDC30...etc) Space = 0gb
I can not see the drive in disk management, or device manager.
I am running version 2.7 of the Motherboards BIOS.
I have been reading forum posts all day and can't find anything useful. I think my board is UEFI as it is brand new 2011 board, although I saw that Gigabyte released 3tb unlocker utilities for earlier Motherboards (Not X79).
I have tried switching the sata port it is attached to, restarting, booting into win 7 install disk (To see if I could format it there).
All of the help about this is concerned with the 2.2 tb problem or the 746 gb problem. This isn't either of those.
Thank you so much in advance for all your help.

In your bios can you make sure "hot swap" is enabled. I had a weird thing happen before where I could not see more than 3 drives in Windows unless all the drives were hot-swap enabled on my board.
Do you have AHCI enabled?
ACHI is enabled for most drives. But the main controller is set as IDE.
Where would I choose the Hot Swap option? I cant seem to find it.
EDIT: When I changed the onchip Sata Controller from IDE to ACHI I got an error loading operating system on a black screen. Had to restart.
