7.3 Jumper settings 7.3.1 Jumper pin assignment There are four jumper settings as shown in the following sections: 16 logical heads (normal use), 15 logical heads, 2GB clip, and auto spin disable. Each category is exclusive. The pin assignment of the 9-pin jumper used to select "Device 0" or "Device 1", "Cable Selection" and "Device 0 Forcing Device 1 Present" is shown below. The Device 0 setting automatically recognizes device 1 if present. The Device 0 Forcing Device 1 present setting is for a slave device that does not comply with the ATA specification. Note: In conventional terminology 'Device0' means 'Master' and 'Device1' means 'Slave.' RSV GND GND GND RSV I G E C A HFDB DS CS/SP GND RS V Figure 43.
