On the Maxtor D740X-6L 20.0/40.0/60.0/80.0GB AT hard disk drives, the ATA
bus interface cable connector (J1, section C) is a 40-pin Universal Header, as shown
in Figure 3-9.
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 6, “ATA Bus Interface and ATA Commands,” for more detailed
information about the required signals. Refer to Table 6-1 for the pin assignments
of the ATA bus connector (J1, section C).
