On the Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB 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).
