Hi Kazy, & welcome to Tom's Hardware!
Can't really tell from the UTube what is HDD noise. The title indicated it is a Veloci-Raptor 10,000 RPM drive.
The clicking noise I heard at the start of the clip is not a normal finding, usually means trouble.
Here is a website that permits you to listen to all the abnormal sounds HDD make, for comparison, and what they mean:http://datacent.com/hard_drive_sounds.php
After comparing "sounds", I'd either just call WD directly, Tele # 800-275-4932 , and talk to them about it (they will record the drive Model and SN), or just send it back for a warranty replacement from NewEgg.
