 	Internal drive is SCSI ID 0, system is ID 7.  Drive has been configured
 	as ID 1, 2, 3, and 4.  Terminators have been place integral to 
 	the drive, as well as on the SCSI cable itself.  Terminator power has
 	been specified  as coming from the drive itself (not from the Mac.)

You have too many terminators.  There is one on the Internal drive, one set
in the Wren, and one one the cable.  Take off the cable terminator.

NB:  Wren terminators are 3 SIP resistor packs on the edge of the circuit
board nearest the SCSI connector.  They are socketed.  Remember the orientation
if you remove them.
