Hardware Installation
WARNING! Hard drives and storage enclosures require careful handling, especially
when being transported. If you are not careful with your hard disk, lost data may
result. Always handle your hard drive and storage device with caution. Be sure that
you are properly grounded by wearing an anti-static strap when handling computer
components or discharge yourself of any static electricity build-up by touching a large
grounded metal surface (such as the computer case) for several seconds.
1. Using a Philips head screw driver (not included), remove the side mounted screw on
the left front facing side of the enclosure.

2. To reveal the drive bay, grasp the front panel and slide it upward.
3. With the hard drive label facing upward, gently slide each of your 3.5” hard drives
into the drive bays until you feel resistance.
Instruction Manual

4. Slide the front panel back onto the S32BU33HR the same way it was removed.
5. Using a Philips head screw driver (not included), replace the side mounted screw on
the left front facing side of the enclosure.

6. Using the included power adapter, connect the Power Adapter Port on the
S352BU33HR to an available power outlet.
7. Connect the S352BU33HR to your computer system using the included
USB 3.0 cable.
8. Set your desired RAID conguration and power on the device.
WARNING! In order to prepare your drives for RAID operation, this enclosure will
congure newly installed drives into your desired RAID conguration. Please be
aware that any data currently on the drives may be lost during this process. It is
recommended that you back up all data prior to setting your RAID conguration.
Instruction Manual
6
a) Ensure the S352BU33HR is powered o.
b) Adjust the RAID Control Switch to your desired RAID conguration (See Available
RAID Congurations).
c) Press and hold the set RAID button while turning on the S352BU33HR on by
pressing the Power Button.
Note: RAID conguration is only required for initial conguraiton or if you would like to
change your RAID conguration.
Available RAID Congurations
The S352BU33RER enclosure supports 4 dierent RAID congurations. RAID is a
storage technology that combines multiple hard drives into a single unit for secure
data redundancy, increased volume size and/or improved performance.
Descriptions and benets for each available RAID conguration are listed below:
JBOD - Normal
In JBOD, no RAID conguration is set and both drives appear as individual disks.
Note: For both drives to be detected while connected via eSATA the host controller
must support SATA Port Multiplier.
Instruction Manual
7
Combine - BIG
In BIG, both drives appear together as a single large disk the size of both drives
combined. This conguration enables you to create a larger volume than would be
available using a single drive without the performance increase oered with RAID 0.
R1 (RAID1) – Mirroring
In RAID1 both drives appear as a single disk and data is written identically to both. This
level protects your data from individual drive failure as a backup of all data is written
instantly.
R0 (RAID0) – Spanning
In RAID0 both drives appear together as a larger single disk the size of both drives
combined. This level can improve your performance as read and write operations are
performed in parallel on separate disks.
How to Use
Accessing your Array
Once the enclosure has been attached to a computer, and powered on, your computer
system will automatically recognize the drive(s) and it will be accessible as though it
were installed in the system internally.
Note: If your computer fails to automatically recognize your drive it is likely your
drive has not been initialized or formatted correctly. (See Drive Initialization below for
further instructions.)
LED Indicators
The hard drive enclosure oers LED indicators so you can monitor drive and RAID
array activity. Do not remove the enclosure from the host computer while the LEDs are
ashing, as it could damage the drive or the enclosure, resulting in data loss. Please see
the table below for detailed LED indication.

Disconnecting the Hard Drive
Windows
1. Select the “Safely remove Hardware and Eject Media” icon, located in the task bar.
2. Select the Mass Storage Device from the list that appears.
3. Wait for the message indicating that it is now safe to remove the device.
Note: Removing the connected drive prior to receiving notication that it is safe
to do so, could result in losing or corrupting data stored on the drive. Once the Safe
to Remove Hardware message appears, please disconnect the enclosure from the
computer by removing the USB connection.
Mac OS X
To safely disconnect the attached drive from the host computer, close any windows
listing the contents of the removable drive. Once all windows are closed, click on the
USB storage icon on the desktop, and drag it to the Trash Can icon on the desktop.
Allow 5 seconds before physically removing the enclosure/drive from the computer.
Instruction Manual
11
Initializing the Hard Drive
1. If the drive array is new it may need to be initialized and formatted before use. From
the main Windows desktop, right-click on “My Computer” (“Computer” in Vista/ 7
/ 8), then select Manage. In the new Computer Management window, select Disk
Management from the left window panel.
2. A dialog window should automatically appear, asking you to initialize the drive.
Depending on the version of Windows, it will give you the option of either creating
an “MBR” or “GPT” disk. GPT (GUID partition) is required for drives larger than 2TB
but is not compatible with some older operating systems, while MBR is supported
by newer and older operating systems.
Instruction Manual
12
3. Once initialized, locate the Disk that says it is “Unallocated” (check the listed hard
drive capacity to conrm it’s the correct hard drive) and then right-click in the
section that says “Unallocated” and select “New Partition”.
4. Several on screen prompts will follow walking you through the steps to create the
partition. Follow these prompts to complete partition creation.
