Periodic Noise from Head Movement WD Black 4TB

Why in the world would tech support not just say what the problem is with the thumping noise, instead of letting me run a test that takes over 8hrs for a 4tb drive?

Obviously the guy in tech is either new, or wants to avoid their customers complaints. I have the Be Quiet Dark Base Pro 900 Case with Silent wing 3 fans and Noctura DH-15 Cooler which comes with excellent and very quiet fans.

Also I have tinnitus and still hear the bloody noise thump… thump… thump as if someone was in my backyard hammering on something. Not impressed as all my drives over the years (since window inception) have been WD when purchasing new drives and none of them made this stupid sound.

Any advice on dampening the sound?
