FOR SAFE OPERATION
Handling of This Manual
This manual contains important information for using this product. Read thoroughly before using
the product. Use this product only after thoroughly reading and understanding especially the
section "Important Alert Items" in this manual. Keep this manual handy, and keep it carefully.
FUJITSU makes every effort to prevent users and bystanders from being injured or from suffering
damage to their property. Use the product according to this manual.
This product is designed and manufactured for use in standard applications such as office work,
personal devices and household appliances. This product is not intended for special uses (atomic
controls, aeronautic or space systems, mass transport vehicle operating controls, medical devices
for life support, or weapons firing controls) where particularly high reliability requirements exist,
where the pertinent levels of safety are not guaranteed, or where a failure or operational error could
threaten a life or cause a physical injury (hereafter referred to as "mission-critical" use). Customers
considering the use of these products for mission-critical applications must have safety-assurance
measures in place beforehand. Moreover, they are requested to consult our sales representative
before embarking on such specialized use.

Preface
This manual explains concerning the 3.5 inch hard disk drives with internal Serial
Attached SCSI (SAS) controller.
The purpose of this manual is to provide the specifications and functions of SAS
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.
The organization of this manual, related reference manual and conventions for
alert messages follow.
Overview of Manual
This manual consists of the following six chapters, glossary, abbreviation, and
index:
Chapter 1 SAS Interface
This chapter describes the topology, physical and electrical requirements, interface
protocol, and other operations of the interface.
Chapter 2 Command Processing
This chapter describes the basic logical specifications related to command
processing.
Chapter 3 Data Buffer Management
This chapter describes the data buffer configuration, data transfer processing
functions and cache operations.
Chapter 4 Command Specifications
This chapter describes detailed command specifications and how to use them.

Preface
ii C141-C009
Chapter 5 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.
Chapter 6 Disk Media Management
This chapter describes the procedure for initializing the disk media, methods of
treating media defects and data recovery methods.
Glossary
The glossary explains technical terms which are necessary to the reader’s
understanding when reading this manual.

CONVENTIONS USED INTHIS MANUAL
The model names of the disk drives covered by this manual differ depending
on their device types and capacity (*1). In addition, these disk drives are called
Intelligent Disk Drive (IDD), "drive" or "device" in this manual.
Note: Model Name
M AU 3 147 RC
Interface type
Formatted capacity (1,000MB units)
* 1MB=1,000,000bytes
Disk size 3: 3.5 inch
2: 2.5 inch
Type AU: 3.5 inch height, 15,000rpm
AT: 3.5 inch height, 10,025rpm
AV: 2.5 inch height, 10,025rpm
Decimal numbers are represented normally.
Hexadecimal numbers are represented as shown in the following examples:
X’17B9’, 17B9h, 17B9H, or 17B9H.
Binary number is represented as "010", 010b.
An X is used to represent mode parameters that are ignored by the MODE
SELECT and MODE SELECT EXTENDED commands. An X is also used
to represent mode parameters reported by the MODE SELECT and MODE
SELECT EXTENDED commands and that vary depending on conditions at
the time.

Conventions for Alert Messages
This manual uses the following conventions to show the alert messages. An alert
message consists of an alert signal and alert statements. The alert signal consists of
an alert symbol and a signal word or just a signal word.
The following are the alert signals and their meanings:
This indicates a hazardous situation likely to result in
serious personal injury if the user does not perform
the procedure correctly.
This indicates a hazardous situation could result in
serious personal injury if the user does not perform
the procedure correctly.
This indicates a hazardous situation could result in
minor or moderate personal injury if the user does
not perform the procedure correctly. This alert signal
also indicates that damages to the product or other
property, may occur if the user does not perform the
product correctly.
This indicates information that could help the user
use the product more efficiently.
In the text, the alert signal is centered, followed below by the indented message. A
wider line space precedes and follows the alert message to show where the alert
message begins and ends. The following is an example:
(Example)
It is possible to use bit 7 and bit 6 of the control byte as an inherent
control field in future product specifications. It is recommended that
the INIT specify zero in this field.
Attention
Please forward any comments you may have regarding this manual.
To make this manual easier for users to understand, opinions from readers are
needed. Please write your opinions or requests on the Comment at the back of this
manual and forward it to the address described in the sheet.
