I think we would want to test bit 6 of IDENTIFY DEVICE word 83, issue SET 
FEATURES - SPIN UP command if set,
otherwise do a READ VERIFY or some other media access command

The word-2 signature values already give us that information,
and I'm not certain that we can rely upon word 83 even being
"present" when a drive has not spun up.  I see lots of zeros
in the upper words of the IDENTIFY info from drives in this state.
