Thanks, Francois.  After some testing, I've determined that drive is definitely flaky and fortunately I'm still within the vendor return window.Tim

I'll say some specific parts of the magnetic platters of your drive are
damaged and that's why you get this error every time trying to access the same

A drive has not to be old to fail; failure during the first weeks of activity
is relatively common.
It may have been badly packaged or handled during transport or may have been
badly manufactured ...
