    "New HDD, WD Black WD2003FZEX Thumping Noise every 3-5 seconds"

In another thread, a commenter says it even happens if the
drive is powered, and has no data cable connected.

An attempt to search on "WD2003FZEX firmware update" yields
nothing sensible, implying no update is available.

When a drive light flashes once a second on a PC, disconnect
the optical drive data cable, and see if the flashing
continues.

Apparently that drive also makes the "motor noise" at shutdown.
I have a WD2004FBYZ that makes a funny noise at shutdown,
as if the motor spindle doesn't have a bearing at the top.
Motor bearings can have two bearings (used until the motor
is spinning fast enough), or one bearing. And at some
point WDC seemed to switch motors to something that
"drags a bit" when powering down. The deal with hard
drive noises is, "the more noise a drive makes, the more
likely it is to fail".

My "pinball-machine" Seagate years ago (before the year 2000),
it used to make quite a noise when the heads would "unlock"
at startup. And one day, that thing did not release properly.
And the competing forces inside the drive, ground the heads
into the platter until the motor stalled. There was a loud
"sproing" noise as well, like a clock mainspring, which was
a sound likely coming from the arm with the heads on it.
I didn't need to run a diagnostic that day :-/ You don't
need a diagnostic when the sound effects are suitably loud.
They could at least have had a car-crash sound come out of the
computer speakers.
