Brand new corrupt drive

I've recently purchased an additional Hitachi Deskstar P7K500 320gb SATA HD to compliment my other Hitachi 80gb HD on my home build PC. I hooked it up and Vista didn't recognize the new drive. I went and manually set up the drive, and as soon as i put something on it, Vista gave me a (back up and replace drive) message. Any suggestions?
 
Run hitachi's diagnostic tools on it, if it fails, RMA it. If it passes looks like you are safe.
