There should be a terminator at each end of the SCSI bus.  Typically,
you don't have to worry about the processor end.  Old Seagate drives
have internal termination resistors that need to be removed if the
drive is not at the end of the bus or you are using an external terminator.
The Seagate web site has user guides online for all models.  The Toshiba
CDROM probably has a switch to disable the internal terminator.
