That looks suspiciously like a cabling/termination/whatever problem.
Termination: start and end of SCSI cable, NEVER in the middle.
Cabling: Use identical, high-quality SCSI cables. Between two connectors
there needs to be at least 15 cm cable (internal drives). External boxes
_need_ to have the internal connector _between_ the external plugs, should
supply terminator power, and should NOT have internal terminators -- that's
the job of the terminator you plug into the open end of the external bus.
If you still have these "pass-through" terminators, take your hot glue gun
and close the open end. Now. There's absolutely no use for it.
If in doubt, open the boxes to make sure.
Whatever: Does every device have parity recognition enabled?
