Most third party SCSI HD manufacturers terminate the drive internally.  This
is done to make the drive a "plug -n- play" device for most users who are new
to SCSI devices.  It begins to be a pain in the a$$ if you wish to hook up
more than one SCSI device in daisy chain fashion.

If you ever need to add another SCSI device to an internally terminated SCSI
HD (for those of you that can afford it), you need to open the HD's case, find
2 or 3 rectangular plastic looking pieces that have prongs sticking out of one
side.  You probably can't see the prongs, they're stuck into a socket. 
Anyway, CAREFULLY pull them straight out using a chip puller or pliers.  Now
your SCSI interface can pass through to the next device.  Save them
terminators in case you ever need to terminate the HD again.  They're kinda
fragile, so be careful.
