How to Use
Connecting the Hard Drives
Once the enclosure has been attached to a computer, and your the drivers will install
automatically, and the inserted drives will be accessible as though they were installed
within the system.
Prior to using the drive array, it will need to be formatted according to your operating
system requirements. Refer to Initializing the Hard Drive
LED Indicator
The hard drive enclosure oers LED indicators for each drive, so you can monitor drive
activity. The LED will ash while the hard drive is being accessed. Do not remove the
enclosure from the host computer while the LED is ashing, as it could damage the
drive or the enclosure, resulting in data loss.
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 notication 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
drive icon on the desktop, and drag it to the Trash Can icon on the desktop. Allow 5

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.
3. Once initialized, locate the Disk that says it is “Unallocated” (check the listed hard
drive capacity to conrm 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 the prompts to complete partition creation.
