WD back grinding noise

Solution
Well, it's hard to tell from that recording, but it sounds like normal operating noises. WD blacks are pretty loud compared to their blue/green drives; it's not unusual to be able to hear them while they are actively reading/writing.

As for the vibration - if it's just a slight, high-frequency vibration that you can only feel when touching your case, then that's pretty normal as well - platters spinning at 7200rpm will inevitably cause some vibration and it's pretty easy to transmit that from the hdd to your case. My 7200rpm external hdd vibrates my entire desk a bit when it spins up.

I use wd blacks [all my drives are blacks ] and theres no sound from them. near as if there was no drive at all

run the wd data life guard for you drive and see how that goes - to me if your hearing it as you say sounds like something has failed or failing [opinion]

also if you look around the hard drive section here at toms theres a wd rep you can private message as well

I would not go for that best answer at all

I have 3 WD blacks and they all make clearly-audible noises similar to what he recorded when doing random-read/write-heavy tasks. I also have multiple WD Red Pros, which are basically the same drive with some extra features tacked on, and they make the same noise under the same conditions.

If you don't believe me, then maybe look at the many professional reviews of black drives that mention the noise levels. My point is that noises coming from a WD black does not mean it is broken or failing.

Running diagnostics on the drive never hurts, though.

It's highly unlikely that of the 6 drives (3 black, 3 red pro) that I bought, ALL of them are defective in the exact same manner. I bought them at different times as well, so it's not like I just got stuck with a crappy batch either.

I've had two of the drives for 2 years and one for 1 year, and they show no signs of malfunction (other than the noise if you want to count that).

And again, if you don't believe me, here are some professional reviews that mention the noise:
