Hi, I have edited this post as I found a software solution for the annoying bug.
This is an issue with most WD drives I have read, but can be really bad depending on the batch your drive comes from.
The clicking or clunking noise is from the drive doing a LCC (parking heads) and is a power management (APM) issue and needs to be a configurable firmware fix from WD for those who want it. I have used Hard Disk Sentinel to disable APM or set to 254, LCC is now a 0 per day, which is what it should be considering WD Black drives are for performance. As you can see from the image, LCC has stopped, the first day was without any adjustment, 2-4 was with WD3IDLE and 5 with APM disabled.
It is a big issue, as it is only suppose to park the heads when the hard drive is not is use for the allocated time, 8 seconds in my case.
You don’t need the software to stay in memory as once disabled, it stays disabled until the drive is powered down, so a simple run of the software will stop it.
I found QuietHD/WD3IDLE do not work correctly, only Hard Disk Sentinel.
I have no idea why a hard drive needs to park the heads at regular intervals when there is obviously no sign of a power save needed.
I am going to look into making a small startup program to do this. Annoyed I have to do anything at all, last time I buy WD drives.
Please fix WD.
