Master/slave jumpers

If you already have one hard drive in your computer and you are
installing a second drive, you must configure one drive as a mas-
ter and the other as a slave.
Note. If you need to change the jumpers on your existing hard
drive, see the Disk Manager online manual, look on the
drive label, or contact the drive manufacturer.
To configure the drive as a master or one drive only:
•
The drive is configured at the factory for a master or single-
drive operation with a jumper set on pins 7 and 8.
Note. The master drive usually defaults to being the "boot" drive
(drive C), from which the computer loads system soft-
ware when it first starts up.
To configure the drive as a slave:
•
Remove the jumper to configure the drive as a slave.
