I don't disagree but I'd like to find something more concrete or 
repeatable, especially given that these give an audible click when 
failing.  The problem I'm having is that I can't nail down precisely 
where the problem is, although your suggestion makes a lot of sense.

After running Justin's suggested badblocks test, I'm kind-of-disturbed 
to see that all these drives are passing with flying colors.

Firmware issue?  WD had it in the past.
