I've just seen this exact problem with the exact same numbers.  The
drive is dead or dying.  I'm hoping mine comes back enough to grab the
data still on it.  When it works it works without error and passes short
smartctl tests.  I think the disk surfaces are probably okay and it's
the electronics that are almost gone.  If I find any sequence that seems
to get it initialized and working, albeit for a short time, I'll post.
