WD has a bunch of utilities and some will work on "any" drive.
Some will work on "any" drive ONLY IF it can find a WORKING WD drive
in the system.  And some of the lower level utilities will ONLY work on a
WD drive and (may) tell you the "other" drive(s) are not supported.
If I remember correctly, this specific utility falls into the last category.
In any event, (as in lots of computer things) there is no one answer unless
you get very specific. (You were...)
Note the "Catch 22" in finding a "working WD drive" category...
Some times you can't test a drive because it is not working. An interesting twist.
