Hard Drive Installation?

So I just got a 3.5 inch Hitachi 1 terabyte SATA hardrive. I plugged it in, made sure it was detected in the BIOS, made sure it was detected in the Device Manager, and then looked in My Computer. Its not there. All that shows up is my 80 gig. I am running Windows Vista Ultimate 32-bit. I looked at device manager again. My hitachi shows up so i figured everything was ok. I looked in properties and looked for the "format" and "initialize" but found none. Any help please? I need to get it to show up on My Computer!
