Preface
This manual describes MHT2080BH/ MHT2060BH/ MHT2040BH models of the
MHT Series, 2.5-inch hard disk drives. These drives have a built-in controller
that is compatible with the Serial-ATAinterface.
This manual describes the specifications and functions of the drives and explains
in detail how to incorporate the drives into user systems. This manual assumes
that the reader has a basic knowledge of hard disk drives 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.
Acronyms and Abbreviations
This section gives the meanings of the definitions used in this manual.

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 to be used in offices or computer rooms.
Conventions
An MHT 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.
Serial-ATA may be referred to as "SATA."

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 drive 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.
