WD RED 4TB Vibrates


I did buy 2 WD RED 4TB, drives plugged in Synology DS1813+ one drive is vibrating lot is that normal?

Synology S.M.A.R.T Quck / Extended   test says drive is ok.


Take a look at this link. It refers to vibration.

How to tell if the noise or sound the drive is making is normal 

Today i did put that disk to external usb bay i can detect vibrations on desk when disk is 70cm away.
