Firstly, I am not trying to run raid AT ALL.
I downloaded the SATA raid driver from the link FlashDude gave me and installed it, no effect.
The new HDs are installed correctly, when I touch them they are warm and vibrating slightly, so they must be getting power at least. I have also triple checked to make sure the cables are secure.
diskmgmt.msc does not show anything except my current HDs and my DVD drive.
Also, I am using the Gigabyte sockets, it is the Intel ones that do not work at all, no matter what is plugged into them. I have checked the manual and any documentation is realated to the Gigabyte controler.
