Chain goes:

GS
Apple HS SCSI Card (Terminated :)
25-50 SCSI cable
pass-through SCSI terminator
Quantum HD (not terminated)
50-50 SCSI cable
Quantum HD (not terminated)
50-50 SCSI cable
Syquest 44 (not terminated)
pass-through or end-cap SCSI terminator

-or-

GS
Apple HS SCSI Card (Terminated :)
25-50 SCSI cable
Quantum HD (terminated)
50-50 SCSI cable
Quantum HD (not terminated)
50-50 SCSI cable
Syquest 44 (terminated)

The consequence of too much termination appears
to be that drives "down the chain" aren't visible.

The consequence of too little termination appears
to be "soft" crashes as your files and file structure
become corrupted.

Too much termination is safer to recover from than
too little?
