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

Importanty Back up all important data stored in the PATA 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 PATA 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 PATA 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 PATA Mirror Drive securely using themounting 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 PATA Mirror Drive.
The host computer may even fail to recognize it due to BIOS timeout settings.

1 3.5” Form Factor PATA Mirror Drive Functions
Incorporating two SATA 2.5-inch Hard Disk Drives, the STR-V 3.5” Form Factor PATA Mirror Drive
uses mirroring technology to safeguard data and to provide uninterrupted operations.
Since the host computer will recognize the PATA Mirror Drive as a standard PATA HDD, installing the
PATA Mirror Drive simply involves connecting it to a PATA cable from the host computer.

1.1 Featuresz Supports Mirroring technology (RAID Level 1) implemented via hardware thereby reducing systemoverhead.
z In the event that one of the drive unit fails, the PATA 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 Parallel ATA interface, the PATA Mirror Drive can be used likeany other standard Parallel AT HDD.
- No special device drivers needed.
- Compatible with most operating systemsz Compact size
- 3.5” HDD Form Factor Full Compliant- 101.6 mm x 146.8 mm x 25.4 mm (W x L x H)
z Parallel ATA Interface conforming to ATA/ATAPI-6 Specifications- UDMA 100 (Ultra DMA Mode 5) Compliant with a maximum data transfer speed of 100MBps at thehost 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 Driveis 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, datais written to and read from the other drive unit.

1

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

1.3 Cache Buffer Function
The PATA Mirror Drive is equipped with a large cache memory capacity. With write cache mode
enabled, the PATA Mirror Drive will signal completion of command processing to the host computerwhen 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 PATA Mirror Drive. Write cache mode is enabledthru a DIP Switch. The default setting at shipment is "enabled".

Important

Always observe the shutdown procedure specified for the hostcomputer’s operating system. In delicate situations, try to wait atleast 10 seconds to be sure that both the access indicator and thedrive status indicator have stopped flashing before shutting off thepower. Turning off the power while the access indicator or thedrive 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.
not turn off the host computer while the PATA Mirror Drive is still
Caution Do
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 PATA
Mirror Drive skips copying the bad sector and continues to reconstruct the remaining data. Theseskipped sectors will no longer be readable. Once some data is written to this sector, it can be readcorrectly again.

Important

If the data recovery process skips some sectors during datarebuilding, 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 PATA 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 PATA
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 PATA Mirror Drive still responds to the host normally even during reconstruction. After thereconstruction is finished, the PATA Mirror Drive returns to normal mode automatically.
