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.
