We just got a bunch of HP drives in, and the little critters send out an
SDTR message on power up and SCSI bus reset.  This might have a problem with
the initiator software, if it isn't programmed to receive and unsolicited
SDTR message.  Furthermore, the manual says to remove a certain jumper to 
dis-allow the sending of the SDTR message, but it don't work.  The darn thing
sends SDTR with or without the jumper on.
