New SATA HD not showing up in computer; showing up in BIOS

[Total Immortal]

So I just stuck a 1TB SATA HD in my computer, and it's not showing up when I open up My Computer. I've re-started about half a dozen times. I went into the BIOS, and the BIOS sees it. I have very little exerpeience with SATA so maybe I'm just doing something stupid. FWIW, my main HD is on SATA 1 and the new HD is on SATA 3. PLZ HALP!! Thanks

what's happening is the drive hasn't been formatted so it's not showing up in windows because there isn't really anything there. You have to go to disk management and format the drive.

That explains it, thank you! I'm actually going to install a different OS on this HD, so I guess I will just wait till I do that. Thanks!
