Just because it's new doesn't mean it can't die. It's a mechanical device subject to failure. I've had some new drives arrive DOA. It happens. If it's under warranty, have it replaced.
I'd be more worried about the current pending sectors than the spin time. The spin time may just be due to the drive being put to sleep then having to wake up (spin up) again. You can remedy that by going into your power options and tell it never to put the drives to sleep.
