Preface
This manual describes MHW2060AC, and MHW2040AC models of the MHW
Series, 2.5-inch hard disk drives. This drive has a built-in controller that is
compatible with the ATA interface.
This manual describes the specifications and functions of the drive and explains in
detail how to incorporate the drive into user systems. This manual assumes that
the reader has a basic knowledge of hard disk drive and their implementations in
computer systems.
This manual consists of seven chapters and sections explaining the special
terminology and abbreviations used in this manual:
Overview of Manual
CHAPTER 1 Device Overview
This chapter gives an overview of the disk drive and describes their features.
CHAPTER 2 Device Configuration
This chapter describes the internal configurations of the disk drive and the
configuration of the systems in which they operate.
CHAPTER 3 Installation Conditions
This chapter describes the external dimensions, installation conditions, and switch
settings of the disk drive.
CHAPTER 4 Theory of Device Operation
This chapter describes the operation theory of the disk drive.
CHAPTER 5 Interface
This chapter describes the interface specifications of the disk drive.
CHAPTER 6 Operations
This chapter describes the operations of the disk drive.
Glossary
The glossary describes the technical terms that need to be understood to read this
manual.

Preface
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 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
procedure 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)
Data corruption: Avoid mounting the disk drive near strong
magnetic sources such as loud speakers. Ensure that the disk drive
is not affected by external magnetic fields.
The main alert messages in the text are also listed in the “Important Alert Items.”
Operating Environment
This product is designed considering its application in car navigation systems.
Conventions
An MHW series device is sometimes simply referred to as a "hard disk drive,"
"HDD," "drive," or "device" in this document.
Decimal numbers are represented normally.
Hexadecimal numbers are represented as shown in the following examples:
X'17B9', 17B9h, 17B9H, or 17B9H.
Binary numbers are represented as shown in the following examples: 010 or 010b.

Preface
Representation of the data storage capacity in this manual
One gigabyte (GB) = one billion bytes; accessible capacity will be
less and actual capacity depends on the operating environment and
formatting.
Attention
Please forward any comments you may have regarding this manual.
To make this manual easier for users to understand, opinions from readers are

Liability Exception
“Disk drive defects” refers to defects that involve adjustment, repair, or
replacement.
Fujitsu is not liable for any other disk drive defects, such as those caused by user
misoperation or mishandling, inappropriate operating environments, defects in the
power supply or cable, problems of the host system, or other causes outside the
disk drive.
Compliance with Administration on the Control of Pollution Caused by
Electronic Information Products of the People's Republic of China

Important Alert Items
Important Alert Messages
The important alert messages in this manual are as follows:
A hazardous situation could result in minor or moderate personal
injury if the user does not perform the procedure correctly. Also,
damage to the product or other property, may occur if the user does not
perform the procedure correctly.
Task Alert message Page
Normal Operation Data corruption: Avoid mounting the disk near strong
magnetic sources such as loud speakers. Ensure that the disk
drive is not affected by external magnetic fields.
Damage: Do not press the cover of the disk drive. Pressing
it too hard, the cover and the spindle motor contact, which
may cause damage to the disk drive.
Static: When handling the device, disconnect the body
ground (500 kΩor greater). Do not touch the printed circuit
board, but hold it by the edges.
3-6
Damage: Interface cable connection
Take note of the following precaution about plugging an
interface cable (socket) into the interface connector of the
disk drive and plugging the connector into a host receptacle:
−When plugging together the disk drive interface
connector and the host receptacle or interface cable
connector (socket), do not apply more than 10 kgf of
force in the connection direction once they are snugly and
securely in position.
