This publication could include technical inaccuracies or typographical errors. Changes are periodically made to the information herein ­ which will be incorporated in revised editions of the publication. Maxtor may make changes or improvements in the product(s) described in this publication at any time and without notice. UL/CSA/VDE/TUV/RoHS UL standard 1954 recognition granted under File No. [. . . ] This table specifies the number of cylinders, heads, and sectors for a particular drive type. You must choose a drive type that meets the following requirements for the 20, 30 or 40 GB: Logical Cylinders x Logical Heads x Logical Sectors/Track x 512 = 8, 455, 200, 768 4. Boot the system using the operating system installation disk-- for example, MS-DOS--then follow the installation instructions in the operating system manual. 4-18 Quickview 40 20/30/40GB AT Chapter 5 ATA BUS INTERFACE AND ATA COMMANDS This chapter describes the interface between Quickview 40 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 Quickview 40 hard disk drives use the standard ATA/ATAPI interface. Support of various options in the standard are explained in the following sections. 5. 2 5. 2. 1 MECHANICAL INTERFACE Signal Cable and Connector The Maxtor Quickview 40 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. The Maxtor Quickview 40 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 5. 3. 1 5. 3. 1. 1 ELECTRICAL INTERFACE ATA Bus Interface Electrical Characteristics Signals on the ATA interface are assigned to connector pins according to Annex. The signaling protocol complies with clause 9 and signal timing complies with clause 10 of the standard. The Maxtor Quickview 40 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. When power is applied with RESET- asserted, the Maxtor Quickview 40 disk media will not begin to spin up until RESET- is negated. This may reduce maximum current consumption for the overall system. Quickview 40 20/30/40GB AT 5-1 ATA Bus Interface and ATA Commands 5. 4 REGISTER ADDRESS DECODING The Maxtor Quickview 40 hard disk drives allow their host systems to address the full set of command and control registers as specified in clause 7 of the ATA/ATAPI-6 standard. 5. 5 5. 5. 1 COMMAND INTERFACE General Feature Set The µProcessor, Disk Controller, and ATA Interface electronics are contained in a proprietary ASIC developed by Maxtor. 5. 5. 2 Supported Commands The Maxtor Quickview 40 hard disk drives support all the mandatory commands from the general feature set for devices not supporting the Packet command feature set. Refer to the ATA/ATAPI-6 standard for a detailed description of these commands. The IDENTIFY DRIVE command, however, is elaborated in the section "Identify Drive Command" on page 5-5. Table 5-1 lists the supported commands.

[. . . ] The resulting surface is hard, smooth, and capable of storing data at high density. STEPPER ­ A type of motor that moves in discrete amounts for each input electrical pulse. Stepper motors used to be widely used for read/write head positioner, since they can be geared to move the head one track per step. Stepper motors are not as fast or reliable as the rotary voice coil actuators which Maxtor disk drives use. [. . . ]
