Blinks slowly after ejecting successfully

I have a brand new Elements portable 5TB external HDD. It passes all tests and works fine except for one thing.

When I eject the drive from Windows 10 I get a safely ejected message as expected and drive disappears from drive list in my computer but the led on the drive goes into a slow rhythmic blink pattern. Since it is ejected I expected the blink to stop. It never does.

In other forums some people say it blinks because it is still getting some power and merely shows power but is in a safe idle mode. Since it ejected properly it no longer appears in windows 10 drive list.

When I unplug it while still slow blinking no data is damaged. I ran tests.

Does anyone else have a portable Elements HDD that behaves like mine?

Does anyone have the same drive that the led shuts off completely after ejecting but still connected to usb?

My old passport drive behaves exactly the same way and has never failed in years of use.

Hiya. Am experiencing same issue with my 5tb Elements…none of my other brand portable hdd act this way when ejected. There lights go off and there’s no power supplied to them from my laptop. I’ve raised an issue with WD about this, but surprisingly I was informed they have no literature on the led light status, but helpfully advised I have a back up of my back up.
Did you ever find out the truth behind the blinking led?
