Installation

WARNING: Hard drives 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.

Hardware Installation

1. Make sure the power switch on the enclosure is set to OFF and the power adapter is

unplugged from the enclosure.

2. Unlock the drive bay doors by turning the twist lock clockwise with the provided keys.

3. Open the drive bay doors by pulling on the metal door latch forward.

4. Slide a bare 2.5”SATA hard drive into the drive bay and close the door behind it, making sure

it latches properly.

5. Lock the drive bay doors by turning the twist lock counter-clockwise with the provided keys.

6. Set the enclosure to the proper RAID mode via the selection switch on the rear.

7. Connect the power adapter from an electrical outlet to the enclosure.

8. Power on the enclosure by setting the power switch to ON.

9. Press the “Reset” button on the rear of the enclosure to ensure the proper RAID mode

becomes set.

10. Connect the enclosure to the computer via eSATA or USB, not both.

11. To remove drives from the enclosure, rst make sure that the disk volume is unmounted

within the operating system (see documentation for your operating system or host

controller) or the computer is o.

12. Turn the enclosure o by switch the power switch to OFF.

13. Unlock the drive bay door with the provided keys and open by pulling the metal latch

forward.

Driver Installation

No driver installation is required for these operating systems, as this enclosure is natively

supported, so the drivers are already installed.

Instruction Manual 4

How to Congure

Operating Modes

Mode Description

RAID 0

(Striping)

Striping combines multiple disks into a single large disk array.

The data is split evenly across each disk simultaneously. Read/

write performance is increased as a result, but failure of any one

disk will make the entire array unusable.

RAID 1

(Mirror)

Mirroring writes the same data across multiple disks, creating

exact mirror copies. This provides redundancy in case one drive

fails.

JBOD

(Single)

JBOD enables each hard drive to be seen as separate

independent drives. If only a single hard drive is installed,

ensure this mode is enabled.

NOTE: When using eSATA, this mode should only be used if the

eSATA host controller provides Port Multiplier (PM) support. If a

host is not PM-aware, only a single drive will be visible. No such

limitation exists if using the USB connection.

BIG

(Concat)

BIG concatenates multiple hard drives into a single large disk.

Provides no performance or redundancy benets.

Instruction Manual 5

Using the Storage Device

Windows 2000/XP/Vista/7

If you are using a brand new hard drive that does not contain any data, then you will rst

need to prepare the hard drive for use. From the main desktop, right-click on “My Computer”

(“Computer” in Vista/7), then select Manage. In the new Computer Management window, select

Disk Management from the left window panel.

Locate the Disk that says it is “Unallocated” (check 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”.

Instruction Manual 6

The New Partition Wizard will appear. Follow the instructions in the wizard to complete setting

up the drive. Once complete, the Disk should show up as “Healthy” with a drive letter assigned

(i.e. E:). This drive letter should now appear within My Computer.

If you are installing a hard drive that already has data on it, then after plugging it in, the drive

should automatically show up with a drive letter assigned within My Computer.
