PREFACE

This manual explains concerning the MAA3182SC and MAB3091SC series 3.5 inch hard disk

drives with internal SCSI controller.

The purpose of this manual is to provide specifications of each command and detailed

explanations of their functions for use of these magnetic disk drives incorporated into user

systems, and to present the information necessary for creating host system software. This

manual is written for users who have a basic knowledge of hard disk drives and their use in

computer systems.

The composition of manuals related to these disk drives and the range of subjects covered in

this manual are shown in “Manual Organization,” provided on a subsequent page. Please use

these other manuals along with this manual as necessary.

Composition and Contents of This Manual

This manual is composed of the 5 chapters shown below, a glossary and a list of

abbreviations.

Chapter 1 Command Processing

This chapter describes the basic logical specifications related to SCSI command processing in

the MAA3182SC and MAB3091SC series disk drives.

Chapter 2 Data Buffer Management

This chapter describes the data buffer configuration provided in the MAA3182SC and

MAB3091SC series disk drives and concerning data transfer processing functions and cache

operation.

Chapter 3 Command Specifications

This chapter describes detailed specifications of SCSI commands provided by the

MAA3182SC and MAB3091SC series disk drives and how to use them..

Chapter 4 Sense Data and Error Recovery Methods

This chapter describes the configuration and contents of sense data which report to the host

system when an error occurs, etc., key information necessary for error recovery, recommended

procedures for error recovery to be executed through host system software and retry

processing executed internally in the MAA3182SC and MAB3091SC series disk drives for

recovery.

Chapter 5 Disk Media Management

This chapter describes the procedure for initializing the disk media, methods of treating media

defects and data recovery methods for the MAA3182SC and MAB3091SC series disk drives.
