      Hello..
 
          I am a certified hardware technician so maybe I can help...
 
          Jumper SS on a Quantum is the Self Seek Test mode
          This causes th Quantum to perform continuous random
          seek patterns verifing target ID's for ever seek. This
          continues until the HD is powered down or an error
          arrises.
 
          Jumper WS controls the wait/spin option. If enabled
          the HD will not spin on power-up til the host sends
          the START/STOP UNIT command accross the SCSI BUS.
          This is useful to avoid overloading your power-supply
          on power-up.
 
          JUMPER EP controls the checking of parity accross the
          SCSI BUS. When disabled, partiy checking is not performed
          although parity is still generated...
 
                  My Suggestion:  WS disable
                                  EP enable
                                  SS definately disable!
 
                Hope This Helps!
                    -Later
