Yes, I had another look at found that wdc_exec_command is not called
in many places at all :-(  I cannot see why the drive should be
wedging the machine at all.  I am starting to think that the drive
firmware has a bug that is crashing it just on the basis that the
drive shuts down totally when the machine hangs.  I am getting close
to going back to the 410 I had before at least the HD on that was
reliable and there was no weird blue flicker in X :-(
