If this drive was the startup drive previously, or if it's a new hard drive, then the master drive designation will already be set. To change the designation of a new drive to be a slave drive, skip to step 4. 3. Find the jumpers on the circuit board of the drive. Jumpers are plastic plugs with metal sleeves that form a circuit between a pair of pins. Use tweezers or very small pliers to remove or reposition the jumpers to the configuration shown in the documentation or on the disk label.
Jumpers are very small and easy to lose.
Hold your hand over the jumper while removing it to keep it from jumping too far. Store jumpers in a small plastic bag for future use. Avoid touching the pins with the tweezers or pliers to keep from bending the pins. Inc. How things get done. Use of this Web site constitutes acceptance of the eHow Terms of Use and Privacy .
