As long as you terminate the last device on the chain as not to starve
other devices further down. It is generally practiced to have the
termination found at the end of the cable (either the cable or device
attached), but I don't see why you could not termintate in the middle.
Remember that the terminator is absorbing the signal so that it will not
bounce back on the cable to cause interferance. If you were to terminate
as such
SCSI card <----> Terminated Tape Drive <----> UnTerminated SCSI HD
The hard drive could not communicate with the SCSI card in your computer
as the Tape Drive would absorb the signal going both ways.
Hope this helps,
