I recently upgraded my 4TB NAS (wd red) by 8TB wd red pro.
I bought 2 HD. Plugged the first one in (sync of the nas ok). Then plugged the second one in and this one started to act strangely.
It makes 2 clicking noises each 3 seconds (you can imagine how annoying it is)
I discovered this KB: https://support.wdc.com/knowledgebase/answer.aspx?h=p2&ID=20933&lang=en&p=623 but i dont know if it relates to my case though.
I checked the HD with data lifeguard and tried to do a regular format (with windows) and no problem has been detected.
But the repeating clicking each 3 seconds (!) suggests me there is an issue.
What do you think about? Should I contact the support?
