Help!

I bought a new 1 (OEM) TB SATA hard drive to be a secondary drive. The trouble is that when I installed it and turned on my computer the drive is not seen in "My Computer" but IT IS seen in the Device Manager. Yikes. Also when I went into the BIOS both hard drives are seen.

My goal is to format, and partion the second drive so it will work. How can I do this?

Thanks in advance for everyone's kind, kind help!
