Question: Exactly as the title states, the sound that my HDD is making is like gurgling. I went close and it is like a low grumble every few seconds. It is super annoying when I hear it on my side. I just bought this HDD and I was wondering if it could be faulty. I have booted up Windows and tested and everything seems to be fine. Is this a cause for concern?

Answer:

Yea it has just arrived yesterday and I immediately opened it up and installed a new Windows 10 into it.

OK then… Normal for that particular device.

Use it until it dies.
