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 5 above.

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 5 above.
