Sorry. That was a typo.
The WD hard drive is: WD20EZRX (as suggested).

That picture shows the WD drive above that I have.
As you see, there is an empty (and slightly smaller) "slot"
between the SATA connectors and the power connector.

Now I'm looking at one of the drives that works
in my HP SuperMicro drive-bay.
This is the Seagate 250GB Barracuda drive (ST3250318AS)
that came with the machine.
In this the power connector(s) are in the same position
as the empty slot above, although the slot is slightly wider.
This is true of the other 3 drives in my 2 SuperMicros.

(Unfortunately I cannot provide a photo at the moment,
as both my Android phone and my camera are out of action.)
