HDD won't show up in windows

[youngblood1017]

I finally finished my new build and installed windows. I have a Seagate 1tb HDD and a 60gb OCZ Agility 3 SSD boot drive. In the Asus UEFI BIOS both drives showed up but when i installed Windows 7 the HDD didn't work at all it wasn't in the bios and the Asus HDD diagnosis light was on. finally i got it to show up in the bios but the diagnosis light is still on and it still wont show up in My Computer in Windows. What do i need to do to get it to work. Any help would be greatly appreciated. Thank you.

Right click on Computer. Click Manage. Click on Disk Management. The Drive should pop up and asked to be Initialized. If it doesn't scroll down the list of drives and right click on it to Initialize it. Once the drive is Initialized the OS should assign it a drive letter and it will show up in My Computer (or Computer as it is known as in Win 7)
