Ok, AFAICT, the WD diagnostic disc simply used the S.M.A.R.T.
conveyance test, which it aborted. Timing aside, that disc passes
all the tests that smartctl knows about.

I've noticed that top often reports 50% or more hi (hardware interrupt)
when the system is slow, and that drive is being hit. I just did a copy
from that disc to another of a 90MB or so ISO and saw 95.4% hi.
This seems to imply that the disc is signalling completion, and the
controller is generating an interrupt, but then the handler is having
to poll for a while before getting the go ahead from the disc. Is
this normal?
