     This is wrong.  ESDI drives respond to the IDENTIFY command, and
possibly other "ATA" commands.  ESDI is a superset of the original
WD1003 command set, and ATA is a superset of that.

     My old ESDI drive has died, so I can't get you a sample result,
but I have verified that it responds intelligently.
