[SOLVED] WD external 14TB cannot complete the "complete drive test"

[Pextaxmx]

I was going to shuck this drive, then I wanted to do the bad sector test before I do.
Crystal disk info looked spotless.
Model is WDC WD140EDGZ-11B1PA0 14000.5 GB

Downloaded the "WD Drive Utilities" and started the "Complete Drive Test."
Before that I set the Windows 10 "turn off hard drives after" to never. Also turned off the time-off setting in the WD utilities settings.
Test started at Power on hours of 2, now it is 98 hrs. which is longer than 4 full days, and consistent with the clock time.
Does it mean
(1) it is still checking bad sectors
(2) drive is bad, maybe stuck at certain sector?

The drive LED is consistently blinking since I started the test. When I touch the drive case, I can feel the head moving every 20 seconds or so.

Do you think I should stop the test and replace the drive?

Still working.
You have no reason to suspect failure.

the reason I suspect failure is that average time it took from forum postings for this test is about 1 hour per terabytes. I am close to 8 hours per TB - maybe about time to suspect failure? what do you think?
The drive is still behaving exactly same.

1h per TB = 277MB/s - that's fiction. No mechanical drives are that fast. May be only short burst speed at beginning of the drive. Not average drive transfer speed.

8h per TB = 34MB/s - this is slow. Probably USB 2.0 speed is to blame here.

less than 30 MB/s soon.... and I am using USB 3.1 Gen1 port with proper WD cable. I think I am going to bestbuy tomorrow to exchange this drive.

This is the speed I just checked - 1hr/TB is not that far from reality it seems.
