Master/Slave Jumper
Settings
If you already have one hard drive in your
computer and you are installing a second drive, you must configure
one drive as a master and the other as a slave.
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.
To configure the drive as a slave:
- Remove the jumper to configure the drive
as a slave.
 |
NOTE: The
master drive usually defaults to being the "boot" drive
(drive C), from which the computer loads system software when
it first starts up. |

Non-ATA compatible
slave jumper
If your computer does not recognize your
new drive as a master in a two-drive system, the slave drive may
not be ATA-compatible. You may be able to solve this problem by
setting a jumper on pins 5 and 6 and a jumper on pins 7 and 8
as shown in Figure 2 below.
Cable-select jumper
Some computers differentiate between master
and slave drives using specially designed interface cables that
have the line to pin 28 (the Cable select pin) removed or cut
at one connector. The connector that has pin 28 disabled is used
for the slave drive. See your computer manual to determine whether
your computer supports this feature. To configure your drive for
cable select, set a jumper on pins 5 and 6 as shown in Figure
2 below.
