Jumper block information
The jumper block is a block of pins located on the hard drive. When these pins are shorted with shunts
(jumpers), the drive will behave in certain ways. A shunt is a small piece of plastic with metal inside that
shorts out the connection between 2 pins when placed over them. These can be purchased at any local
computer store. The pin pitch for all pins except for Termination Power is 2 mm. Termination Power pins
have a pitch of 2.54mm.
Auto Start Delay
The Auto Start and Auto Start Delay pins control when and how the drive can spin up and come
ready. When configured for Auto-Startup, the motor spins up after a SCSI reset without the need
of a SCSI Start Unit command. For no Auto-Startup, a SCSI Start Unit comand is required to
