Step4: Install the HDD into the tray and insert one screw on each side. Make sure screws are
firmly tightened, holding the tray and HDD together.
Step5: Slide the HDD tray into the case.
Step6: Push the switch to the right side to lock the HDD tray.
5. Raid Settings
You can configure the FANTEC SQ-X2RU3e to use any of the following Storage Policies to
map the appliance's physical hard drives to virtual drives that are visible to the host
computer. The virtual drives are called volumes in the GUI. The host operating system
treats each volume as if it were a single physical drive.
This virtualization allows you to overcome restrictions that are imposed by physical
hard drives, such as speed, storage capacity or data storage reliability
Important: Back up HDD(s) before adjusting RAID switch.
1. Power on the case.
2. Check and make sure both HDDs are installed and both HDD LEDs light up.
3. Connect the case to PC via either USB or eSATA cable. Make sure HDD LED light up.
4. Select HDD Mode from below table by adjusting “Raid Switch”, which is located at the
back of the case.
5. Pin and hold “RAID Reset” for 3~5 seconds. Then HDD mode will change according
to the selection.
6. Format HDDs before they are ready to use.
Note: Refer to Hard Drive Formatting Guide in the below session for detailed
JBOD MODE(Single):
The normal Mode (Just a Bunch of Disks) storage policy enables each hard drive to be
seen separately as one drive. JBOD storage policy is for a standalone (non-cascaded)
Storage Processor or the top-level node of a cascaded configuration, but not for
subordinate nodes. In a JBOD configuration, each physical drive is directly exposed.

BIG MODE (Spanning):
The BIG storage policy concatenates a series of physical hard drives as a single large
volume; resulting in a seamless expansion of virtual volumes beyond the physical
limitations of singularly connected hard drives. BIG storage policy delivers maximum
storage space without a single large capacity and costly hard drive. Hard drive A and B
are concatenated into a single virtual volume in the Figure below with a storage capacity
that is equal to the sum of each of the physical hard drives A and B.

RAID 0 (Striping):
The RAID0 storage policy distributes access across all hard disks, also called striping.
RAID0 presents the best data speed but no data redundancy. RAID0 storage policy
accelerates hard disk operating speed by using many disks in parallel. Hard drive data
segments are written to different disks simultaneously which increases performance
while sacrificing data redundancy. To implement the RAID0 storage policy, the device
creates a single virtual volume that is striped across both hard drives, with a storage
capacity that is equal to the sum of both hard disk drives.

RAID 1 (Mirroring):
The RAID1 storage policy stores all data in duplicate on separate drives to protect
against data loss due to drive failure. One drive mirrors the other at all times.
Every write operation goes to both drives. RAID1 provides the highest level of data
protection for critical data that you cannot afford to lose if a hard drive fails, but halves
the amount of storage capacity because all data must be stored twice. The resulting
storage capacity of the virtual RAID1 volume will be equivalent to the size of one hard
drive (if both drives are the same) or the smaller of the two drives (if they are different).
If one drive fails, the RAID1 volume is still usable, but it is in a vulnerable state because
its mirrored hard drive is inaccessible. When the offline drive comes back online, the
appliance begins a rebuild process immediately to restore data redundancy. Although
the volume remains available during the rebuild process, the volume is susceptible to
data loss through damage to the remaining drive until redundancy is restored at the end
of the rebuild and verification process. Host access takes precedence over the rebuild
process. If you continue to use the SAFE volume during the rebuild, the rebuild process
will take a longer time to complete, and the host data transfer performance will also be

6. HDD Formatting Guide
STEP1: Right-click on “My Computer” icon and select ”Manage” column.
STEP2: Select “Disk Management” and you will see your External HDD showed
Example:250GB & 750GB hard drives.
JBOD MODE (Single)
Disk 1: 232.88GB
Disk 2: 698.63GB
Disk 1: Capacity = 232.88+698.63 => 931.52
Disk 1: Capacity = 232.88 x 2 > 465.77 (GB)
Disk 1: Capacity = 232.88 = 232.88 (GB)
STEP3: Right-click the circled block and select “Initialize Disk”
STEP4: Press “OK” button to initialize the hard drive.
STEP5: Right-click on the “Unallocated” block and select “New Partition”.
STEP6: The “New Partition Wizard” will appear. Please follow the instruction of the wizard to
STEP7: When partitioning is completed, the external HDD will be recognized as a “New
STEP8: Double-click “My Computer”. You will see the new volume appears on your PC.
Initialize a Disk
If the HDD is new you have to initialization the device. View the box to the left of the
“Unallocated” box.You most likely would see the “Not Initialized” message displayed.
The Hard Disk Drive must be set to “Online” before partitioning and formatting the
Hard Disk Drive.
1. Right-click the “Not Initialized” area, a disk’s initialization menu will appear as below.
Select “Initialize Disk” and follow the steps of the HDD Formatting Guide wizard to
complete disk initialization.
Note: Windows Vista and 7 will ask what kind of disk type you want to make, “MBR” or
“GPT”. Please Activate MBR if the total volume is less than 2TB. If the total volume is
more than 2TB please activate GPT.
7. Note
About HDD Mode
 Reset the device is necessary every time HDD Mode changes. Press Raid Reset button
only when the device is powered on & connected to a running PC.
 Make sure to back up all files before HDD mode changes since such practice requires
HDD reformatting.
 procedure how to change the HDD
a. Install both HDDs to the case
b. Connect the case and PC and have both devices powered on.
(USB connection is proposed.)
c. Adjust RAID switch correctly.
d. Push and hold Raid reset button for 3-5 seconds to observe rapid blinking of both
HDD LEDs. HDD mode adjustment is complete when LED rapid blinking stops.
e. Initialize and format the HDD(s).
 When using two HDDs of unequal capacity, users may experience capacity reduction
under RAID0 and RAID1 configuration. Therefore, it is recommended that HDDs of
equal capacity are used to utilize the application.
About HDD Capacity Support
 Installing HDD(s) over 2TB is possible. However, make sure to run this device under
Vista® and Win7® OS and activate GPT mode when formatting this device to have it
work correctly.
About Power synchronization feature
 This case detects PC power status and turn on & off itself automatically. When PC
power off and/or hibernates, HDD(s) spin down and all LEDs and Fan off, except that
Power LED remains constantly on until main power is shut down.
 In some OS, when system reaches sleep mode, only monitor and peripheral are
turned off while motherboard is powered on. In this case, HDD and LED will be still
About USB & eSATA Connectivity
 The equipped USB3.0 port is downward compatible with USB2.0
 eSATA host(PC) needs to support Port Multiplier function in order to have Normal
Mode(Single) to connect 2 HDDs correctly.
 If eSATA host(PC) doesn’t support hot swappable plug and play function,
Please try following procedure:
a. Connect eSATA cable when case and PC are powered off.
b. Power on case first and observe HDD Link LED(s) are light on
c. Power PC on
This practice procedure is every time reconnection necessary.
 Connecting USB & eSATA simultaneously is impossible. eSATA connection will be
About Fan
 This case is equipped with manual fan speed control for faster/slower fan.
However, in order for efficient heat dissipation, it is strongly recommended that max
speed (adjusting to the right-most, +) is set at all time.
 Fan synchronizes along with power synchronization function. After the case reaches
sleep mode, the fan stops within 2 mins.
