New WD20EARX making strange noise

Hi,

I have a new WD20EARX in operation since the other day and notice some strange noise.

I have tried to capture a little footage as good as possible: ► YouTube footage

Please ignore the pulsating high frequency noise, I don't know where that came from because it's not audible in real life.

Make sure to turn up the volume or use a headphone in order to hear the click noise.

I also noticed that the HDD in question (right hand side) vibrates significant more than my approx 18 month old HDD (on the left hand side). The temperatures of both HDDs are rather low, being 36 ºC @ idle.

HDD Healt and WD Data Life guard confirm the HDD to be alright.

Would you think that might still be an RMA case?

Thank you

Have you changed or disabled head parking with wdidle3?

Hi, no I haven't changed anything.
Afaik this only should be use for certain HDDs.
