Scrubbing noises in HDD even after changing the drive.

[Smrtka]

Hello All,

When my machine is idling (or not doing much), I get this strange noise from my HDD like the needle scrubbing over the plate and then parking back, now I initially thought my drive is about to die, even tho HD sentinel was showing full Health, so I have replaced my WD with a Seagate HDD, but that drive makes the same noise.
Now this might be something obvious to someone, but is this some sorts of buffer setting to keep the drive active or cashed ?
my OS is on SSD and I have another SSD for games, the HDD is mainly used as an games library over spill and large storage.

Thanks

I have a 1000W platinum PSU, any way I can test this ?
The noise is also not constant it just makes the scrub noise, and then quiet for a minute and again for 2 seconds and so on.

I believe it could be either of those two above, as I both drive do it one is WD green and other is Seagate, is this something I can disable in windows or just have to live with.
Funny you never notice this issue when the OS is running on the HDD as its spinning constantly.
