D. Take the transport paper
board out of the device.
E. Slide 4 HDDs into the chassis and
make sure they are securely
installed in order from up
to down.
F. Adjust the metal frame that was removed
in Step C. Please make sure the
bottom of the frame stays
inside the track before
closing the cover.
G. Connect the power supply to the device, plug in either USB or eSATA
cable in the rear panel and power on the device.
First install the HDD from up to down in the enclosure. Power on the device,
press RAID button for 3 seconds until LED flashes. Press it again, select the RAID mode
you want to use and press the Confirmation Button on the rear panel till the device shuts down.
Power the device on again and the RAID mode setup is completed.

MIRRORING
This mechanism provides an improved performance and fault tolerance similar to
RAID 5 but with a dedicated parity disk rather than rotated parity stripes.
The single parity disk is a bottle-neck for writing since every write requires
updating the parity data. One minor benefit is the dedicated
parity disk allows the parity drive to fail and operation will continue
without parity or performance penalty.
RAID 10
Mirroring + Striping RAID 10 is mirrored(Raid 1) sets in a striped(Raid 0) set .
Spanning concatenates multiple hard drives as a single large volume; resulting in a seamless
expansion of virtual volumes beyond the physical limitations of separately connected
hard drives. The data are written from HDD1 to HDD4.
Distributed parity requires all drives but one to be present to operate; drive failure
requires replacement, but the array is not destroyed by a single drive failure.
Upon drive failure, any subsequent reads can be calculated from the distributed parity
such that the drive failure is masked from the end user.
The array will have data loss in the event
of a second drive failure and is vulnerable until
the data that was on the failed drive is rebuilt onto a replacement drive.
Raid 0, JBOD Spanning Only , Non-Single JBOD
Striping is a method of concatenating multiple hard drives into one logical storage unit.
It is the automated process of writing data across .multiple drives simultaneously.
Striping is used to increase the performance of disk reads. The multiple hard drives will
write data in “column” effect. If one drive in a striped set fails, all of the data in the stripe
set is lost.
Mirroring is the automated process of writing data to multiple drives simultaneously.
Mirroring is used to provide redundancy. If one drive fails, the redundant drive(s) will
continue to store the data and provide access to it.
The failed drive can then be replaced
and the drive set can be rebuild.

If the HDD is uninitialized, you may have to initialize
it by doing steps as followed: At first click “Start”,
“Execute” at your PC and key in “diskmgmt. msc”.
After that please press “RETURN” key.
1. Start disk initialization.
2. Create new partition and format disk.
3.HDD format completed

Note: Please enable GPT if the total capacity is more than 2TB and enable MBR if the
total capacity is less than 2TB.

Move the cursor of your mouse to the bottom left corner and right click “Run”.
If the HDD is uninitialized, you may have
to initialize it by doing steps as followed:

1. Changing the RAID mode will cause data lost.
2. Please refer to the instructions when switching the RAID mode, otherwise the execution
might fail.
3. Interface of USB / eSATA can not be used at the same time.
4. When using RAID function, HDDs with the same brand, model and capacity is strongly
recommended.
5. When using RAID function, more than one HDD partition is not recommended.
6. Under Windows Vista / 7, users can enable GPT when initializing HDD with a total capacity
of more than 2TB.
7. Older OS may not recognize the device if you use a different operation system than
Windows Vista / 7. For more detailed information about GTP, please visit:
http://www.microsoft.com/whdc/device/storage/GPT FAQ.mspx
8. If users enable MBR by mistake, in order to clean the partition table, you have to switch to
another RAID mode and do the RAID mode switch all over again referring to Setup.
Then go back to the RAID mode you want, repeat the previous actions and enable
GPT when initializing HDD.
9. For Macintosh users: the total capacity of more than 2TB could be recognized only for the
operation system is 10.4.11 Tiger or later.
10. Do not connect the device to the SATA on board port of the motherboard.
Either use SATA to eSATA PCI-Express or SATA to eSATA PCI add-on card,
otherwise the PC (Windows / Macintosh) may not recognize the device.
11. In RAID 1, HDD1 and HDD2 must be installed, otherwise the PC (Windows / Macintosh)
can not recognize the device.
12. Rebuild time is based on the capacity, e.g. it takes about 1 hour for 200GB.
13. When the USB / eSATA cable is plugged out, the device goes to sleeping mode
automatically.

19. If the noise is still present, you can change the fan with another identical fan
of size 80x80x20mm referring to Figure-2.
14. To take the HDD out from the device, slightly press down the handle of the tray
and pull it out.
15. Setting up motherboard's power management in S3 is recommended.
(For more details, please refer to the user guide of motherboard BIOS setting).
16. If the device takes too long to initialize, please check if the HDD is securely installed or
update the eSATA host driver version.
17. If the transfer rate is not normal, please check if the setting of SATA disk jumper
is 1.5 or 3.0Gbps .
18. If there is noise with the fan, power off the device, unscrew the fan, take out the cover ,
clean the fan and assemble it back.
