ATA Bus Interface Connector (J1, Section C)

On the Maxtor DiamondMax Plus9 60/80/120/160/200GB AT hard disk
drives, the ATA bus interface cable connector (J1, section C) is a 40-
pin Universal Header, as shown in Figure 3-6.
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, "ATA Bus Interface and ATA Commands," for more
detailed information about the required signals. Refer to Table 5-1 for
the pin assignments of the ATA bus connector (J1, section C).
