This manual describes MHV2120AT, MHV2100AT, MHV2080AT, MHV2060AT,
MHV2040AT model of the MHV Series, 2.5-inch hard disk drives. These drives
have a built-in controller that is compatible with the ATA interface.
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:

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 to be used in offices or computer rooms.
Conventions
An MHV 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, 17B9
Binary numbers are represented as shown in the following examples: 010 or

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.

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 kΩ or greater). Do not touch the printed circuit
board, but hold it by the edges.
Damage: Interface cable connection
Take not 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.

The disk drive is 2.5-inch hard disk drives with built-in disk controllers. These
disk drives use the AT-bus hard disk interface protocol and are compact and
reliable.
C141-E218 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) Gr een pr oduct
The disk drive is lead (Pb)-free products and the European Parliament and
Council Directive on the Restriction of the use of certain Hazardous Substances in
electrical and electronic equipment (the RoHS Directive) compliant.
(3) Large capacity
The disk drive can record up to 60 GB (formatted) on one disk using the RLL
recording method and 30 recording zone technology. The disk drive has a
formatted capacity of 120 GB (MHV2120AT), 100 GB (MHV2100AT), 80 GB
(MHV2080AT), 60 GB (MHV2060AT) and 40 GB (MHV2040AT).
(4) High-speed Transfer rate
The disk drive (the MHV Series) has an internal data rate up to 41.3 MB/s. The
disk drive supports an external data rate up to 100 MB/s (U-DMA mode 5).
(5) Aver age posit ioning t im e
Use of a rotary voice coil motor in the head positioning mechanism greatly
increases the positioning speed. The average positioning time is 12 ms (at read).
1.1.2 Adaptability
(1) Power save mode
The power save mode feature for Idle operation, Standby and Sleep modes and
automatically power down by APM function makes the disk drive ideal for
mobile use where power consumption is a factor.
(2) Wide tem perature range
The disk drive can be used over a wide temperature range (5 °C to 55 °C).
(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 1.5B [MHV2040AT]/2.3B [MHV2060AT,
1-2 C141-E218
1.1 Features
MHV2080AT, MHV2100AT, MHV2120AT]. The Sound Pressure level is 16dB
[MHV2040AT]/24dB [MHV2060AT, MHV2080AT, MHV2100AT,
MHV2120AT], as measured 0.3 m from the drive in Idle mode.
(4) High resist ance 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) Connect ion t o ATA int erface
The disk drive has built-in controllers compatible with the ATA interface.
(2) Data buffer
The disk drive uses 8MB 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 (7), 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) Master/slave
The disk drive can be connected to ATA interface as daisy chain configuration.
Drive 0 is a master device, drive 1 is a slave device.
(5) 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.
(6) 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.
(7) 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.

1.2.2 Model and product number
Table 1.2 lists the model names and product numbers of the disk drive.
The model name does not necessarily correspond to the product number as listed
in Table 1.2 since some models have been customized and have specifications
that are different from those for the standard model.
If a disk drive is ordered as a replacement drive, the product number must be the
same as that of the drive being replaced.
