The i-Stor RAID
Features mentioned
in this manual may
vary between
different models.
When it comes to raw power there is nothing to beat the new
dual-bay i-Stor. Available in the classic Pleiades design, the iStor is built strong and rugged, offering more than enough
capacity to store all your digital media files. Not only that, the iStor RAID can also back up and secure all of your data thanks
to RAID protection.
Product Dimensions:
24.5cm x 13.3cm x 7.6cm

About Data Backup
To protect your files and help prevent the loss of your data, we
strongly recommend that you keep two copies of your data,
one copy on your i-Stor and a second copy either on your
internal drive or another storage media such as CD, DVD, Tape
or an additional external drive. Any loss or corruption of data
while using the i-Stor is the sole responsibility of the user, and
under no circumstances will the manufacturer be held liable for
compensation or the recovery of this data.

Chapter 2 - Hard Drive Assembly
Your unit may come with a pre-installed hard drive. Before
opening such an enclosure, please read the warranty from your
vendor carefully, as this could void your warranty.
i-Stor RAID
1. Remove the four screws at the bottom of the case.
The aluminium
stand does not
have to be removed
for drive assembly.
2. Push the inner enclosure out, and remove the outer chassis.
3. Install the first hard drive and mount it with two screws on
each side.
For RAID 0 and
RAID 1, identical
hard drives are
recommended
(same manufacturer,
capacity and RPM)

4. Install the second hard drive and mount it with two screws
on each side.
Be careful not to
damage any cables
or components, and
make sure the
cables are
connected firmly.
5. Connect the SATA and power cables to your hard drives. Be
careful not to damage any components and confirm that the
cables are connected firmly.
6. Slide the inner enclosure back into the outer chassis.
7. Fasten the four screws to finish the assembly.

before you plug it
into the wall
socket.
Connection to your Computer
A few tips on how to use your external storage enclosure:
• Check the cables for visible damage before turning it on
• Do not expose the product to water or humid conditions
• Do not cover the enclosure’s ventilation holes
Hard Disk Mode
When using your i-Stor, the disk will mount to the first
connection that is presented. This will remain the default setting
until the device is next restarted.
When not in use, turn off the power. For the hard drives to go
into stand-by with the Operating System, we recommend using
SATA II hard drives set up as RAID 0 or RAID 1.
If you use a 6-pin
FireWire cable,
make sure not to
insert the connector
the wrong way
around, or you will
damage the device!
Changing the
RAID setup will
require you to reformat the drives.
Make sure you
backup all data
before doing so!
RAID Setup
Non-RAID: The drives will show up as two independent drives.
Use this if you have only installed one drive or two different
drives (not the same capacity and brand).
JBOD or RAID 0 - Spanning: The two drives show up as one
large single drive. Spanning is an array (not RAID) that is
written sequentially across the two drives. By itself, it does not
provide any performance or redundancy benefits.
RAID 0 - Striping: Used where speed is the primary objective,
RAID Level 0 (also called "striping") is not redundant, and
therefore does not technically conform to the definition of a
RAID. This form of array splits each piece of data across both
of the drives in segments; since data is written without any form
of parity data-checking, it allows for the fastest data transfer of
the other modes. However, if one drive becomes damaged, the
whole array can become corrupted.
Page 6 / Chapter 3 - System Set Up
i-Stor - RAID
User Guide
RAID 1 - Mirroring: This mode requires 2 identical drives to
implement. A RAID 1 creates an exact copy (or mirror) of a set
of data on the second drive. This is useful when reliability and
backup are more important than data capacity. The available
capacity to the user will only be as large as a single drive but
when one of the hard drives fails, it can be replaced and the
data rebuilt automatically.
The i-Stor enclosure has an LED indication at the front to show
the status of the hard drives. As long as both HDD1 and HDD2
are working OK, the LED is green. When a drive fails, the
corresponding LED will turn red. To replace the faulty drive, do
the following:
The LED indication
for HDD1 is
referring to the hard
drive connected to
CN1, where HDD2
is referring to CN2.
When restoring the
data, the rebuild
LED will flash
yellow when the
data is copied from
HDD1 and green
when the data is
copied from HDD2.
1. Turn off the i-Stor and remove both the power supply and
the interface cable.
2. Open the enclosure and replace the faulty hard drive
(HDD1=CN1, HDD2=CN2).
3. Finish the assembly and connect the power supply but do
not connect the interface cable to your computer yet.
4. Turn the power ON and let it rebuild the data. If it rebuilds
from HDD1 to HDD2, the rebuild LED will flash yellow,
where from HDD2 to HDD1 it will flash green.
5. Wait for the rebuild LED to stop flashing.
6. When the rebuild is finished, connect the interface cable to
your computer. Done.
Note: Rebuilding the data might take several hours, depending
on the capacity of your hard drives. As reference, an 80GB
HDD will take about 2 hours to rebuild.

Installation on a PC
Before connecting the device, setup the RAID mode using the
switch at the back of the enclosure. See pages 2-3 and 9-10 for
more details about the RAID setup.
If the system
doesn’t recognise
the drive, turn on
the power first,
before connecting
the interface cable
or connect the
device before
booting your
Operating System.
If the drives have been pre-installed and setup already, you do
not need to change anything, unless you prefer a different
setup.

Remove Procedure
For the safe removal of your drive and to assure that no data is
lost, always follow the correct unplug procedure. Otherwise, an
error message will appear.
• Click on the taskbar icon for external hardware

Partitioning & Formatting
If the drive does not
appear, make sure
the drivers are
installed properly
and the power is
turned on!
Be aware that this will destroy all your existing data on the
drive, so make sure you have a backup! This step is usually
only required the first time you install a factory new hard drive,
if you change the format or want to erase all data on your drive.
PC running Windows
Disk Management Program
• Right click on “My Computer” and choose “Manage”
• Select “Disk Management”
• Choose the drive you want to format and right click on it for
further commands (Choose New Partition)
• Follow the Partition Wizard to setup the drive
Mac OS can not
write to NTFS
formatted drives. To
use your device on
both platforms, we
recommend you to
use FAT32.
If the JBOD or
RAID mode is
enabled, you will
only see one large
drive instead of two
separate hard
drives.
For Win2000, WinXP and Windows Vista, we recommend
formatting the drive using the NTFS file system.
If you are using the FAT32 file system to format the drive on
Win2000, WinXP or Windows Vista, the biggest single partition
you can create will be 32GB. To create larger partitions, you
need to use a 3rd party application or change to NTFS format.

Mac OS
For Mac OS X, use the Disk Utility to format and create
partitions on your external disk.
If the drive does not
appear on the
desktop, make sure
there are no
extension conflicts
and the power is
turned on!
• Select “Disk Utility” in the utilities folder
• Choose your external drive and format it according to your
requirement
For Mac OS X, we recommend formatting the drive using the
native Mac file system HFS+ also known as Mac OS Extended.
If you want to use your drive on a PC running Microsoft
Windows as well as on your Mac, we recommend you to use
the FAT32 file system. On your Mac, select MS-DOS when
formatting it. Note: The file size for a single file on FAT32 is
limited to 4GB.
If the JBOD or RAID mode is enabled, you will only see one
large drive instead of two separate hard drives.
