ATA BUS INTERFACE AND ATA COMMANDS
This chapter describes the interface between the Quickview 300 hard
disk drives and the PATA bus. The commands that are issued from the
host to control the drive are listed, as well as the electrical and
mechanical characteristics of the interface.
5.1 INTRODUCTION
Maxtor Quickview 300 hard disk drives use the standard ATA/ATAPI
interface. Support of various options in the standard are explained in
the following sections.
5.2 MECHANICAL INTERFACE
5.2.1 Signal Cable and Connector
The Quickview 300 hard disk drive contains a 40-pin unitized
connector for both signal and power connections as well as
configuration jumpers. The dimensions and specifications of the
unitized connector comply with Annex. A in the ATA/ATAPI standard.
The Quickview 300 drives require the use of an 80 conductor cable
(ATA/ATAPI-6, Annex. A, Figure A.4 and description) to support the
drive’s Ultra DMA capability.
5.3 ELECTRICAL INTERFACE
5.3.1 PATA Bus Interface
5.3.1.1 Electrical Characteristics
Signals on the PATA interface are assigned to connector pins according
to Annex. A in the ATA/ATAPI-6 standard for the 80 conductor cable
assembly. The signaling protocol complies with clause 9 and signal timing
complies with clause 10 of the standard.
The Quickview 300 hard disk drives support all Ultra DMA Data Transfer
modes (0 - 5) defined in the ATA/ATAPI-6 standard and are ATA/ATAPI-
7 compliant. In addition, these drives support Mode 6, and can send and
receive data at the full 133MB/s transfer rate.
