All SCSI busses must be terminated at each end. SCSI host adapters often
terminate one end, but you must terminate the other end. Some drives
have terminators built-in, on older disks it's a resistor pack you plug
in or remove.

Check to make sure the drive in the middle of the bus isn't terminating
(check manufacturers docs to find out how they do it) and make sure the
disk on the end of the bus IS terminating. If the end disk doesn't have
a built-in terminator you will need to add one to the SCSI cabling after
the last disk on the bus.

Also, check your disk SCSI ID number. You cannot duplicate SCSI ID's on
a single bus.
