3.0 ATA interface

The drive uses an ATA-2 interface. The interface is in compliance with

ANSI ATA (AT Attachment) Interface X3T9.2/143 Rev. 4.0 ; SFF 8011:

ATA Timing Extension for Local Bus Attachments, Rev. 2.0 and SFF

8019: Identify Drive Data for Drives Under 8 GB . This section lists the

ATA commands supported by the drive on pages 27 and 28. Commands

and features with specific applications for the drive are also discussed in

this section. For more information on Seagate's implementation of the

ATA interface and commands, see the Seagate ATA Interface Manual,

publication number 36111- xxx .

The ATA interface consists of single-ended, TTL-compatible receivers

and drivers using an asynchronous interface protocol. The drivers can

sink up to 24 mA and drive a load up to 300 pF. The integrity of the ATA

interface is affected by the interface cable. It is designed to support a

40-conductor, nonshielded interface cable with a maximum length of 18

inches (46 centimeters).

The signal name and signal direction for each I/O connector pin is shown

in Figure 7 on page 26. See the Seagate ATA Interface Reference

Manual , publication number 36111- xxx , for a complete description of

each pin.

Signal names are shown in upper-case letters. If the signal name is

followed by a minus sign (–), the signal is active low. Otherwise, the signal

is active high.
