Hard Drive Making Noise

[Heywhatsup]

Hi there guys, I recently bought a WD Black 6TB 7200 RPM HDD and it's been making a weird knocking/rewinding sound every 3-4 seconds.With a headset on I can't hear it but you can hear it across the room which gets a bit annoying. There's no data on this drive yet, it's freshly installed. I ran the WD diagnostic tool and it came up clean.

 

Here's a video I took: 

 

Is this noise normal? 

 

Thanks.

Oh I see, alright thanks I'll give it a week and see how it goes. Even if it doesn't fault, I'll probably end up returning it if I can't get used to this sound... Appreciated.
