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 for mobile system as notebook PCs, and to be used
within environmental specification. (please refer to the Chapter 1 in this manual.)

disk drive.
C141-E259 iii
Preface
Hot Plug
These drives support Hot Plug which is based on Serial ATA Revision 2.5
Specification.
However, the disk drive installation and removal notes on safety precautions with
regard to hot-plugging vary depending on the specific requirements and
environment-related conditions of the system to which the drive is connected by
hot-plugging.
When using the drive under general conditions of use (i.e., without hot-plugging),
observe the important alert messages and notes on safety precautions given in this
manual.
For the electrical recommendation to the host system which supports hot-plugging
with this drives, refer to Section 5.1.6.

Normal Operation
Maintenance
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 kΩ or greater). Do not touch the printed circuit
board, but hold it by the edges.
Static, Damage
1. Don’t install or remove a PCA or connect or disconnect
a cable or connector plug when the drive is powered.
This may give you an electric shock.
2. Keep away from mechanical assemblies in the unit
during operation. This may cause injuries.
3. Avoid dangerous detergent when the disk drive is
cleaned.

Important Alert Items
Task Alert message Page
Maintenance
Device damage
1. Before touching a PCA or the drive, wear a wrist strap
and perform the human body grounding to discharge
static electricity from your body. This will prevent
irreparable damage to the PCA and the head of the drive.
2. Don’t install or remove a PCA or connect or disconnect
a cable or connector plug when the drive is powered.
This will prevent electrical damage to the disk drive.
3. Operating the disk drive with one or more PCA missing
will be unpredictable. Only power the drive with all
boards installed.
4. Avoid any detergent which may cause short circuits
when cleaning assemblies.
5. Keep all vents open opened and unblocked. Avoid other
conditions which may cause circuits to overheat.
6. Do not apply excessive force to the cover under any
circumstances. Doing so may cause irreparable damage
to the cover.
Device damage
The DE is completely sealed. Do not open the DE in the
field.

7-3
Data corruption
When asking for repair, save all data stored in the disk drive
7-4
beforehand. Fujitsu Limited is not responsible for any loss of
data during service and repair.
Device damage
The disk enclosure (DE) must never to be opened in the field.
7-14
Opening the disk enclosure may cause irreparable damage.
Damage or Device damage
1. Perform any removal after the system power is
7-15
completely disconnected. The cable must not be
disconnected and the screws that attach the drive must
not be removed with the power ON.
2. Do not move the drive and attach or detach the connector
until it comes to a complete stop (about 30 s after the
power is turned OFF).
3. Perform the human body grounding to discharge any
static electricity from your body. (Be sure to wear a
wrist strap)

Overview and features are described in this chapter, and specifications and power
requirement are described.
The disk drive is 2.5-inch hard disk drives with built-in disk controllers. These
disk drives use the SATA interface protocol which has a high-speed interface data
transfer rate.
C141-E259 1-1
Device Overview
1.1 Features
1.1.1 Functions and performance
The following features of the disk drive are described.
(1) Compact
The disk drive has up to 2 disks of 65 mm (2.5 inches) diameter, and its height is
9.5 mm (0.374 inch).
(2) Environmental Protection
The disk drive comply with the Restriction of the use of certain Hazardous
Substances in electrical and electronic equipment (RoHS) directive issued by
European Union (EU).
(3) Large capacity
The disk drive can record up to 80 GB (formatted) on one disk using the RLL
recording method and 30 recording zone technology. The disk drive has a
formatted capacity of 160 GB (MHW2160BJ), 120 GB (MHW2120BJ), and
80 GB (MHW2080BJ) respectively.
(4) High-speed Transfer rate
The disk drive (the MHW2xxxBJ Series) has an internal data rate up to
96.2 MB/s. The disk drive supports an external data rate 3.0 Gbps (300 MB/s)
(Serial-ATA Generation-2). And the disk drive realizes a high performance by
high-speed transfer rate combined with Native Command Queuing (NCQ).
(5) Average positioning time
Use of a rotary voice coil motor in the head positioning mechanism greatly increases
the positioning speed. The average positioning time is 10.5 ms (at read).
1.1.2 Adaptability
(1) Power save mode
The disk drive is ideal for applications since it supports the power save mode
function that works in each of the Idle, Standby, and Sleep modes and has the
Partial and Slumber interface power management functions. And automatically
power down by APM function makes the disk drive ideal for mobile use where
power consumption is a factor.
(2) Wide temperature range
The disk drive can be used over a wide temperature range (5 °C to 60 °C at DE
surface)
1-2 C141-E259
1.1 Features
(3) Low noise and vibration
In Ready status (while the device is waiting for any commands), the Sound Power
level of the disk drives in idle mode is 2.0B [MHW2080BJ] / 2.5B [MHW2120BJ,
MHW2160BJ]. The Sound Pressure level is 23dB [MHW2080BJ] / 29dB
[MHW2120BJ, MHW2160BJ], as measured 0.3 m from the drive in Idle mode.
(4) High resistance against shock
The Load/Unload mechanism is highly resistant against non-operation shock up to
8820 m/s
2
(900G).
1.1.3 Interface
(1) Connection to SATA interface
The disk drive has built-in controllers compatible with the SATA interface.
(2) Data buffer
The disk drive uses the data buffer to transfer data between the host and the disk
media.
In combination with the read-ahead cache system described in item (3) and the
write cache described in item (6), the buffer contributes to efficient I/O processing.
(3) Read-ahead cache system
After the execution of a disk read command, the disk drive automatically reads the
subsequent data block and writes it to the data buffer (read ahead operation). This
cache system enables fast data access. The next disk read command would normally
cause another disk access. But, if the read ahead data corresponds to the data
requested by the next read command, the data in the buffer can be transferred instead.
(4) Error correction and retry by ECC
If a recoverable error occurs, the disk drive itself attempts error recovery. The
ECC has improved buffer error correction for correctable data errors.
(5) Self-diagnosis
The disk drive has a diagnostic function to check operation of the controller and disk
drive. Executing a diagnostic function of the smart command invokes self-diagnosis.
(6) Write cache
When the disk drive receives a write command, the disk drive posts the command
completion at completion of transferring data to the data buffer completion of
writing to the disk media. This feature reduces the access time at writing.
