yDo 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.
yTurn 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.
yDo 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.
yDo 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.
yStore 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.

Important
yBack 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.
yDo not block the ventilation openings of the HDD. Lack of cooling airflow may lead to hard disk drive
failure.
yWait 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.
yNever 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.
yWhen installing it in the host computer's bay, mount the SATA Mirror Drive securely using the
mounting screws provided (0.49 Nm is recommended).
yIn 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.

1.2 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 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
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.
Important
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 Do not turn off the host computer while the SATA Mirror Drive is still
rebuilding the data to prevent loss of data or failure.
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.
If the data recovery process skips some sectors during data
rebuilding, then the data on these sectors will be lost.
Important Periodic backup is recommended.

3.5" 3Gbps-Speed SATA Mirror Drive Model User’s Manual
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.
