3.3 Jumper settings

3.3.1 Master/slave configuration

The options jumper block shown in Figure 1 is used to configure the drive for operation. It is the 8-pin dual

header between the interface connector and the power connector. Use the following settings to configure the

drive as a master or a slave.

Master or single drive. The drive is configured at the factory for a master or single-drive operation with a

jumper set on pins 7 and 8.

Drive as slave. Remove all jumpers.

Drive as master with a non-ATA-compatible slave.

Use this jumper setting only if the drive does not work as a master with no jumpers installed.

Figure 1. Master/slave jumper settings

3.3.2 Cable-select option

Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28,

CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To

enable cable select, set a jumper on pins 5 and 6 as shown in Figure 1. Refer to your computer manual to

determine whether your computer supports this option.

3.3.3 Alternate capacity jumper

Some older computers may “hang” at startup if their BIOS detects a disc drive with a capacity greater than 32

Gbytes. This limits the drive’s capacity to 32 Gbytes when the alternate capacity jumper is used. To access the

full capacity of the drive, you can:

• Update the BIOS

• Use third-party software such as DiscWizard

™

or Disk Manager

• Use a third-party host adapter

For drives with capacities greater than 32 Gbytes, the alternate capacity jumper changes the total available

LBA sectors to 32 Gbytes to solve issues with some BIOS during power on. The ATA Set Features subcom-

mand “F1

Report Full Capacity Available” causes Identify Data words 60 and 61 to report the full capacity.

See Section 4.1.3 on page 32 for more details on the Set Features command.
