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, 17B9H, or 17B9H.
Binary numbers are represented as shown in the following examples: 010 or 010b.

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 |

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-E217 |
1-1 |
Device Overview
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
9.5mm (0.374 inch).
(2)Green product
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 50 GB (formatted) on one disk using the RLL recording method and 30 recording zone technology. The disk drive has a formatted capacity of 100 GB (MHV2100AH), 80 GB (MHV2080AH), 60 GB (MHV2060AH) and 40 GB (MHV2040AH) respectively.
(4) High-speed Transfer rate
The disk drive (the MHV Series) has an internal data rate up to 59.4 MB/s. The disk drive supports an external data rate up to 100 MB/s (U-DMA mode 5).
(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 12 ms (at read).
(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 temperature 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 2.2B [MHV2040AH]/2.6B [MHV2060AH,
1-2 |
C141-E217 |
1.1 Features
MHV2080AH, MHV2100AH]. The Sound Pressure level is
22dB [MHV2040AH]/28dB [MHV2060AH, MHV2080AH, MHV2100AH], 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/s2 (900G).
(1) Connection to ATA interface
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.

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.
