Strange sound on newly RMAed drive

Hi. I have received my RMA replacement yesterday and sent the old one back. The issue is that the new drive is doing a very strange and annoying noise but it functions properly. The broken drive didn’t do the noise and all my drives do not either.

Hello Mate,

How about running the Western Digital DLG tool, you can download it from the wd website.

The disk I am referring to is sent to me by WD and then I sent the broken one back, it’s new. I run the diagnostics and of course there was no problem.
