I got a new hard drive from Newegg today, when I installed it into my PC I couldn't find it on Vista. It wasn't in the My Computer folder, so I had to go to disk management. It shows up on the bottom panel as "Disk 0" and I've already set it to MBR. However, I cannot format it. I have no idea what's going on, and right now my PC is slower, and it still doesn't show up on My Computer. The HD is hooked up by SATA. Also, it's the 3rd hard drive in my PC at the moment, it's not the primary.

How do I troubleshoot it? Is the hard drive bad?

Edit:
Also I know it's the new hard drive on the bottom panel because it says "931.51gb Unallocated" I don't know what happened to 68.49gbs of it but whatever.
