3.5" Form Factor Mirror Drive SATA Model User's Manual
1 3.5” Form Factor Mirror Drive Introduction
The 3.5” Form Factor SATA Mirror Drive utilizes two SATA 2.5-inch Hard Disk Drives and uses
mirroring technology to safeguard data and to provide uninterrupted operation.
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 The 3.5” form factor makes the SATA Mirror Drive easy and convenient to install that will improve
the reliability of the Host system and allows continuous operation for a long time (SVRE-D032SA /
SA1).
Moreover, there is also a separate model that can be installed in a 5.25” open drive bay (half-height) and
have an easy front access (SVRE-D032SA / SA1-B).
z Even if one drive unit fails, the SATA Mirror Drive will continue to function and no data is lost. When
the failed drive unit is replaced with a new one, data will be rebuilt automatically.
z The SATA Mirror Drive uses the industry standard Serial ATA interface and can be used like any
other standard SATA HDD. No special device drivers will be needed and can be used on any host
computer or operating system.
z Conforms to Serial ATA Interface ATA/ATAPI-7 Specifications (maximum data transfer rate: 6Gbps)
It also has a Dip-switch selectable operation mode and function that allows the host side to be
configured as either 6Gbps or 3Gpbs.
z Mirroring technology (RAID Level 1) is implemented via hardware thereby minimizing any overhead
on the system side
1.2 Mirroring
Mirroring technology writes the same data to two drive units simultaneously. If one drive unit fails, data
can still be accessed and read from the other drive unit.
10

3.5" Form Factor Mirror Drive SATA Model User's Manual
1.3 Data Reconstruction
Data rebuilding (the copying of all data from the fully functional drive unit to the new replacement drive
unit) will start automatically and the Mirror Drive is fully usable even if the rebuild process ongoing.
During data rebuild, the drive status indicator of the fully functional drive unit will light green while the
drive status indicator of the replacement drive unit will flash orange.
Also, if the Mirror Drive is rebooted while the data rebuild is in progress, rebuilding will not resume from
the start but from the block prior to the last completed block recorded.
（Refer to「5.1 LED Display」for more information）
Caution
Please make sure to perform the proper shutdown procedure if you want to turn
off the host computer while the SATA Mirror Drive is still rebuilding the data.
Failure to do so may cause the data of the normal drive unit to be corrupted and
rebuilding may not be completed.
When a sector of the fully functional drive unit could not be read during data reconstruction, the SATA Mirror
Drive skips copying that bad sector and continues to reconstruct the remaining data. These skipped sectors
will no longer be readable. However, once another data is written to that sector, it can be read correctly again.
Important
If the data reconstruction process skips any sector during data rebuilding, the
data on this sector will be lost.
Therefore, periodic backup is recommended
1.4 Revival Reconstruction
When something goes wrong in a drive unit and the mirror controller cannot get a response from the
drive within the specified time (30 seconds), the controller will issue a reset command to the drive to
check its status (Background Retry).
If the drive is recovered, the SATA Mirror Drive returns to the normal operation. But if it is not, the SATA
Mirror Drive will shift to revival reconstruction mode.
Revival Reconstruction turns the power of the appropriate drive OFF/ON and if the drive status becomes
ready, reconstruction is automatically started. The SATA Mirror Drive will still respond to the host
normally even during reconstruction. Once reconstruction is completed, the SATA Mirror Drive returns
to normal mode automatically
Revival reconstruction is executed up to two times. On the third time, it will not proceed with the data
rebuild process and will treat the drive as a failed drive. The failed drive status indicator (LED) of the
corresponding drive will light orange.
The revival reconstruction setting function can be Enabled/Disabled by Dip Switch. The default factory
setting is “Enabled”,
