The blinking light of annoyance fix, can anyone help?

I have 2 external USB3 Western Digital external hard drives. A 1TB and a 2TB. When I turn off the computer, one plays along nice and powers down and the little white light stops blinking / being lit. But the 2TB external hard drive light continues to blink. Now the drive itself is not moving, I checked, no noises coming from inside. Now is this a known bug, should I be worried? The hard drive works ok, there are no other problems with it but I still would like an answer to this question. Now here are some specs on the drive in the form of a picture.

I would think it`s more of an issue with the enclosure, dock, not the hard drive. I would say just unplug the thing if it`s not spinning.

No no, it spins down just fine. Everything about the drive says its turned off, except for the light that blinks in a nonstop pattern, as if searching for a host. I tried changing the S states in the bios, didn't work. I tried turning off all the *Allow USB this and that to turn on the computer* didn't work. What about a firmware update, what do you think about that? WD has a universal updated for the firmware, but I am a bit iffy about doing a firmware update on an external HD if you know what I mean. I just want the light to shut off

These are 2 normal WD My book externals ( USB3), both powered externally via a cord attached to a strip.Only the newer 2tb is acting up. They look like this:

This is the other 1tb one that acts normally when powering down my rig. In case you want to see how they differ.

I know the easiest solution would be to simply unplug the drive at night when I go to sleep, but it is far away from my computer, which would mean I have to get up and do it. I am disabled and an amputee below the knee, so it's not out of laziness that I don't want to get up every night before I go to bed to turn it off, it would just be a pain to do so, literally as my leg is not my only problem. I have to live with a shattered lower spine and pelvis. So it's painful getting out of bed at night. It's why I would prefer to solve this without having to get out of bed.

A last-ditch solution would be the Homer Simpson black tape over the light.

Does the light blink even with the USB cable unplugged?

How is USB setting configured in Control Panel\All Control Panel Items\Power Options\Edit Plan Settings\Advanced Settings?

Funny you should ask that. When I unplug from the motherboard, the light shuts off. Here is a pic of the power plan. I have tried USB selective suspend on/off, no change, I tried all the possible configurations with sleep, no change, I basically tried every config you can think of with the power options, the light continues to blink.

One thing I can think off, is that my motherboard is a 970a-ud3 which contains on/off charge for apple devices even when your computer is off, perhaps the external HD thinks, that since there is power in the USB3 ports, the computer is on? But I tried shutting down computer, unplugging it from the power source via the PSU cable, and the damn light still kept blinking. So this is just strange. Something seems to be forgetting to tell the external to power down. It's why I asked about a firmware update.
