ATA BUS INTERFACE AND ATA COMMANDS
This chapter describes the interface between Maxtor DiamondMax10
hard disk drives and the ATA 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 DiamondMax10 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 Maxtor DiamondMax10 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 Maxtor DiamondMax10 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 ATA Bus Interface
5.3.1.1 Electrical Characteristics
Signals on the ATA 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 Maxtor DiamondMax10 hard disk drives support all Ultra DMA Data
Transfer modes (0 - 5) defined in the ATA/ATAPI-6 standard. In addition,
these drives support Mode 6, and can send and receive data at the full
133MB/s transfer rate.
