Figure 4. Non-ATA compatible and cable select jumpers
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-compati-
ble. 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 4.
Cable-select jumper
Some computers differentiate between master and slave drives
using specially designed interface cables, where the line to pin
28 (the cable select pin), is 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 above.
