Question Bad HDD? Power Issue?

I recently installed a brand new Seagate Barracuda 2TB HDD. It started making a clicking noise immediately after the first boot-up, but not the loud knocking sort of clicking. It almost sounds more like a mouse click or beep.

The noise also occurs in a regular pulsing pattern, like a heartbeat, and it only happens when the drive is idle. It immediately stops any time I read or write to the drive, and I've had no issues doing so. I've run tests with Seagate's tools and CrystalDisk, and everything checks out fine. I've tried swapping SATA and power connectors but that hasn't produced a difference.

Here's an audio clip of the sound it's making: https://vocaroo.com/esxWFf4G1Mz

Is this a sign of failure? Maybe a power issue? It doesn't sound like the classic head-knocking to me. I do have another HDD running off the same power cable, but I'm assuming that's not an issue since the cable is designed for that purpose (it has 3 connectors on one cable; I'm using 2).
 
I'm not sure what you are hearing, but Seagate drives perform a Background Media Scan (BGMS) during idle periods.

Data Recovery tools can disable BGMS via the drive's diagnostic terminal port, and this is standard procedure during any recovery. However, Seagate's documentation warns that if you DISABLE_IDLE_ACTIVITY "for an extended period of time drive damage will occur".

Presumably this is to stop the heads from flying over a particular location for an extended period of time, possibly because it affects the platter lubricant coating. In fact IBM released a firmware update for their Deathstars which introduced wear levelling to prevent the heads dwelling too long over the same area thereby reducing the potential for head crashes (according to Wikipedia).

Thank you for the replies. That seems to be my issue. Inconvenient to deal with, but I'm glad the drive isn't failing.
