3.4.3PATA Bus Interface Connector (J1, Section C)

On the Quickview 300 80/100/120/160/200/250/300GB PATA hard disk drives, the PATA bus interface cable connector (J1, section C) is a 40-pin Universal Header, as shown in Figure 3-5.

To prevent the possibility of incorrect installation, the connector has been keyed by removing Pin 20. This ensures that a connector cannot be installed upside down.

See Chapter 5, “PATA Bus Interface and PATA Commands,” for more detailed information about the required signals. Refer to Table 5-1 for the pin assignments of the PATA bus connector (J1, section C).
