Caution

y Do not use the SATA Mirror Drive in locations subject to vibration or shock exceeding t he specified

values. Usage in such locations may result in malfunctions or disk failure.

y Do not use the SATA Mirror Drive in locations or conditions susceptible to condensation. Rapid

temperature change may cause condensation to form in the SATA Mirror Drive. If you think
condensation has occurred, allow the SATA Mirror Drive to acclimate to the new environment. When
there is a rapid temperature change, avoid using the SATA Mirror Drive until it reaches the new
ambient temperature.

y Do not place the SATA Mirror Drive near electronic components with strong electromagnetic fields,

such as televisions or loudspeakers.
Usage of the SATA Mirror Drive in such locations may result in malfunctions or disk failure.

y Turn off the power before moving the unit enclosing the SATA Mirror Drive. This will prevent

damage to the HDD and other internal components of the SATA Mirror Drive.

y Do not turn on the power immediately after turning it off, or turn off the power immediately after

turning it on. Leave at least 20 seconds in-between successive operations involving power on or off.
This will help prevent damage or malfunction to the mounted HDD. The HDD motor spindle requires
about 20 seconds to stop rotating and come to a full rest. In addition, when removing the correctly
functioning drive unit for replacement, turn off the power and wait for at least 20 seconds.

y Do not remove a fully functional drive unit while the power is still on. The SATA Mirror Drive

controller unit will consider the drive unit as failed if it is removed. Removing a fully functional drive
unit may also damage the disk heads and platter inside the HDD.

y Store the SATA Mirror Drive in the antistatic bag. Leaving this product unpacked and unused for a

long period of time may lead to malfunction or disk failure.

y Avoid applying excessive pressure to the covers of the drive unit, which may lead to malfunction or

disk failure.

the power.

iv

3.5" Form Factor Mirror Drive SATA Model User's Manual

Important

y Back up all important data stored in the SATA Mirror Drive to a suitable storage medium, such as

tape drive or MO drive. This product's mirroring technology prevents data loss even if one drive unit
fails. However, if two drive units fail at the same time or if a non-redundant part fails, data loss may
still occur. Additionally, accidental deletion of data or equipment damage may also result in data loss.

y Do not block the ventilation openings of the HDD. Lack of cooling airflow may lead to hard disk drive

failure.

y Wait at least 10 seconds after the access indicator has stopped flashing before initiating the

shutdown procedure for your host computer. The SATA Mirror Drive uses cache memory to store
the data frequently accessed from the HDD. Except in emergencies, you must follow the operating
system's shutdown procedures. Failure to so may result in loss of data stored in cache memory.

y Never remove or exchange the drive units, except to replace failed controller units or drive units,

since the SATA Mirror Drive controls the drive units by using its serial numbers. Thus, removal or
replacement may result in failure to boot up the host computer.

y When installing it in the host computer's bay, mount the SATA Mirror Drive securely using the

mounting screws provided (0.49 Nm is recommended).

y In the event of a drive unit failure, it may take up to 15 seconds to start up the SATA Mirror Drive.

The host computer may even fail to recognize it due to BIOS timeout settings.

1. 3.5” Form Factor SATA Mirror Drive Functions

Incorporating two SATA 2.5-inch Hard Disk Drives, the STR-V 3.5” Form Factor SATA Mirror Drive
uses mirroring technology to safeguard data and to provide uninterrupted operations.

Since the host computer will recognize the SATA Mirror Drive as a standard SATA HDD, installing the

SATA Mirror Drive simply involves connecting it to a SATA cable from the host computer.

1.1 Features

z Supports Mirroring technology (RAID Level 1) implemented via hardware thereby reducing system

overhead.

z In the event that one of the drive unit fails, the SATA Mirror Drive will continue to function,

maintaining data integrity.

- When the failed disk is replaced with a new replacement disk, data rebuilding will begin
automatically.

- Hot plug function is supported at drive interface thereby improving system reliability.

z

Based on the industry standard Serial ATA interface, the SATA Mirror Drive can be used like any
other standard Serial AT HDD.

- No special device drivers needed.

- Compatible with most operating systems

z Compact size

- 3.5” HDD Form Factor Full Compliant

- 101.6 mm x 147 mm x 25.4 mm (W x L x H)

z Serial ATA Interface conforming to ATA/ATAPI-7 Specifications

- SATA-Ⅰwith a maximum data transfer speed of 1.5Gbps at the host interface

- Uses two 2.5-inch SATA drives that supports a maximum data transfer speed of 1.5Gbps

z Dip-switch-selectable operation mode and function
z Self-Diagnostics capability - Power On Self Test (POST) is performed every time the Mirror Drive

is turned on.

z Automatic data reconstruction every time a failed drive is replaced.

- Accepts and processes host commands even during data reconstruction.

z Cache function feature for improved system performance.
z Visual and Audible Status Indicators

- Internal buzzer for audible alarms.

- LED Indicators are provided for direct and visible status checking of each drive and the Mirror

Drive.

- External Status Bit connector is available for special customer-specific indicators.

1.2 Mirroring

Mirroring technology involves writing of data to two drive units simultaneously. If one drive unit fails, data
is written to and read from the other drive unit.

1

3.5" Form Factor Mirror Drive SATA Model User's Manual

1.3 Cache Buffer Function

The SATA Mirror Drive is equipped with a large cache memory capacity. With write cache mode
enabled, the SATA Mirror Drive will signal completion of command processing to the host computer
when data is written to cache memory. The performance will be improved by writing accumulated data to
the HDD when the host computer is not accessing the SATA Mirror Drive. Write cache mode is enabled
thru a DIP Switch. The default setting at shipment is "enabled".

Always observe the shutdown procedure specified for the host
computer’s operating system. In delicate situations, try to wait at
least 10 seconds to be sure that both the access indicator and the

Important

drive status indicator have stopped flashing before shutting off the
power. Turning off the power while the access indicator or the
drive status indicator is still on may result in loss of data currently
located in cache memory.

1.4 Data Rebuilding

If a failed drive unit is correctly replaced, data rebuilding (the copying of all data from the fully functional
drive unit to the new replacement drive unit) will start automatically.

During data rebuilding, the drive status indicator of the fully functional drive unit will light green. The drive
status indicator of the replacement drive unit will blink orange every one second.

Caution

When a sector of the fully functional drive unit can not be read during data reconstruction, the SATA
Mirror Drive skips copying the bad sector and continues to reconstruct the remaining data. These
skipped sectors will no longer be readable. Once some data is written to this sector, it can be read
correctly again.

Important

Do not turn off the host computer while the SATA Mirror Drive is still
rebuilding the data to prevent loss of data or failure.

If the data recovery process skips some sectors during data
rebuilding, then the data on these sectors will be lost.
Periodic backup is recommended.

1.5 Revival Reconstruction

When an error occurs in a drive unit and the mirror controller cannot get the response from the drive for
30 seconds, the controller will issue the reset command to the drive and check its status again.
If the drive recovers, the SATA Mirror Drive returns to the normal operation. But if not, the controller
treats the drive as a failed drive.
The function “Revival Reconstruction” turns the power of the drive OFF/ON. And if the drive status
becomes ready, reconstruction is started.
Revival reconstruction is executed up to two times. After the same error occurs three times, the SATA
Mirror Drive will remain in Degraded Mode. Then the failed drive status indicator (LED) will light orange.
The function can be enabled /disabled by Dip Switch. Factory default is “enabled”.

The SATA Mirror Drive still responds to the host normally even during reconstruction. After the
reconstruction is finished, the SATA Mirror Drive returns to normal mode automatically.
