Most newer drives have a jumper next to the address id jumpers for
termination (old apple cdroms have it as well). Real OLD drives used
3 9-pin resistor packs that had to be inserted or removed for
termination. When dealing with 50pin SCSI 1 and 2, passive
termination is fine. When you get into the 68pin connectors, it is
best to have active termination. Sorry, but I disagree with the
'voodoo' of the bottom post as I have never had any problems with the
position of the device on the cable as long as the termination was in
the correct place. I have always been a SCSI person and frowned when
apple turned to the dark side (IDE/ATA). Cheaper is not always
better.

Also some newer devices may be equipped with "automatic" termination. These
devices are smart enough to know if they need termination or not. If you
don't have a terminator may be best to place this device last in the chain.
Also my Zip drive has a manual switch on the back to set termination off or
on.

SCSI is "Black Magic." I read some time ago, that there are a few rules,
beyond all the known, obvious ones.
Try to put an empty spot between units. Avoid cheap cables.
Put any external HD first, removable drive(s) second, and any scanner dead
last.
Put a terminal block on the 2nd SCSI connector of the last device.
If there are still problems, reset the PRAM.
