In all my limited SCSI experience I've found it is the last Physical device on the cable that needs terminated... Shouldn't matter if the farthest one from the bus is device 1 or 7, if it's on the end, it gets terminated. And that doesn't mean the last plug on the cable, it means the last USED plug on the cable. If I'm off-base, please feel free to correct me. My SCSI is pretty limited.
It's the cable you are terminating, not the drives. It's basic transmission line theory. If the end of a transmission line (SCSI, Ethernet, LocalTalk, etc) isn't terminated with a resistance equal to the lines characteristic impedance there will be a reflection of the signal. This reflection can interfere with the true signal causing an error.
