1.6 Usage Notes

• Use only one interface (USB 3.1 Gen 1 or Thunderbolt) at a time.

• Identical drives (model, capacity, rmware) are required for RAID 0 and RAID 1 congurations.

• During normal drive activity the Drive LEDs will display as solid green while the Activity LED blinks orange.

• If a drive fails or is not connected properly, the corresponding LED will display as solid red.

• If you are building a new array or if you have replaced a drive in a RAID 1 setup and are rebuilding the

array, the Activity LED will pulse orange.

• For the safe removal of your drive and to ensure that no data is lost, always eject or unmount the

corresponding disk(s) from your operating system before powering o. You can use the methods

described below to safely unmount your disk(s).

OS X :

• Drag the icon for the disk you wish to unmount to the trash can; OR

• Right-click the disk icon on the desktop, then click “Eject”; OR

• Highlight the disk on your Desktop and press Command-E.

Windows:

1. Go to the System Tray (located in the lower right corner of your screen). Click on the “Eject”

icon (a small green arrow over a hardware image).

2. A message will appear, detailing the devices that the “Eject” icon controls, i.e., “Safely remove...” Click on

this prompt.

3. You will then see a message that says, “Safe to Remove Hardware.” It is now safe to disconnect

the Mercury Elite Pro Dual from the computer.

OWC MERCURY ELITE PRO DUAL DEVICE SETUP

2.1 Quick Start

Follow the steps below to use the OWC Drive Guide utility to format your Mercury Elite Pro Dual for Mac (OS X

10.6 and later) or Windows (XP and later). If you installed your own drives, please use the formatting method you

are most familiar with or check Section 3.1 for a link to our online formatting tips.

1. Power on the Mercury Elite Pro Dual and plug it into to your computer using the proper data cable. If you prefer

to use a dierent formatting utility, do so at this time and skip the rest of these steps.

2. The disk will mount and your operating system will display it as “OWC SETUP”. Open the disk icon to view its

contents.

3. Double-click the OWC Drive Guide application.

4. Follow the simple on-screen instructions to complete the formatting process. Once the formatting is nished

the drive is ready to use.

2.2 Assembly

NOTE: these assembly instructions are written for users who purchased the Mercury Elite Pro Dual as an empty

enclosure. The instructions show how to open the enclosure in order to install drives. If you purchased the

Mercury Elite Pro Dual with drives already installed, opening the enclosure before the expiration of the original

warranty will VOID the warranty. If you wish to remove or replace the drives after the expiration of the original

warranty, you may do so at that time. You should start with Step 9 in that case and work backwards.

1. Remove the Mercury Elite Pro Dual from its packaging,

then set the enclosure on its side. Use a Phillips PH2

driver to remove the two screws shown at right.

2. Slide the inner chassis out the front of the outer

enclosure, as shown at left. Start by pushing on

the back cover, then grip the front grill and pull the

chassis the rest of the way.

DEVICE SETUP

3. Remove the packet of screws from the inner chassis

and set them aside; they will be used in upcoming

steps.

4. IMPORTANT: before installing the drives, note that each

SATA port on the blue circuit board is accompanied

by a label. These labels are printed on the board and

are located at the base of the two red SATA cables.

The ‘Drive A’ cable corresponds to LED 1 on the front

cover. The ‘Drive B’ cable corresponds to LED 2. This

is important when replacing a failed drive or checking

a drive’s connection.

To continue with the installation, carefully set the rst

hard drive into the inner chassis so that the edge with the SATA ports sits just to the right of the cable connectors

on the circuit board. Connect one set of data and power cables to the corresponding ports on the drive.

5. Set the second hard drive into the inner chassis so it is

aligned above the rst drive. Connect the second set

of data and power cables to the corresponding ports

on the drive. The cables may need to twist or bend

a modest amount; this is OK as long as you do not

crimp the cables and as long as none of the cables

protrude from the back plate once connected.

6. Using eight of the larger screws from the packet

removed in Step 3, fasten the inner chassis to the

hard drives. There are four screw holes on each side

of the inner chassis; you may need to move each

drive slightly to align its screwholes with the holes on

the inner chassis.

7. To determine the correct orientation of the outer

enclosure relative to the inner chassis, turn the outer

enclosure on its side and look at the bottom. As

shown above, the screw holes at the front of the

outer enclosure are close to the silicone feet. The

screw holes at the rear of the outer enclosure are

farther away from the silicone feet.

8. Once you know the correct orientation from Step 7,

slide the inner chassis back into the outer enclosure

as shown.

9. Once the front grill of the inner chassis sits ush with the

edge of the outer enclosure, turn the device on its side

again. The screw holes in the outer enclosure should

line up with the screw holes in the inner chassis. Use

the four smaller screws to fasten the inner chassis to

the outer enclosure, shown above.

This completes the assembly process.

2.3 RAID Settings

2.3.1 Changing the RAID Mode

The RAID mode is controlled by a dial on the rear of the unit, as shown below-left. The dial has four positions,

each labeled with a dierent RAID mode. To change the RAID mode, follow the simple steps below.

Adjust the RAID dial so that the arrow is pointing at the desired RAID mode. Each time the arrow is aligned

with a new mode, you will feel a slight click. A small athead screwdriver works the best to adjust the dial.

When starting from a powered-on state, rst unmount the disk, then

rotate the RAID dial to the desired mode and hold down the SET button

for 3 seconds. The LEDs on the front will blink for a brief time; once the

blinking stops the new array has been built. You can access and format

the disk in the OS at this time.

When starting from a powered-o state, rotate the dial on the back of

the enclosure to the desired RAID mode, then power on the Mercury

Elite Pro Dual and immediately press the SET button for three seconds. The LEDs on the front will blink; once

the blinking stops the new array has been built. You can access and format the disk in the OS at this time.

2.3.2 RAID Modes

RAID 0 “Drive Striping” Mode:

The two drives show up as a single large disk with a size equal to the combined capacities of both drives.

RAID 0 is used when speed is the primary objective; it does not provide data redundancy for protection.

The reading and writing of data les is spread across both drives to gain speed by distributing the workload.

This allows for the fastest data transfer rates, but if one drive fails the whole array becomes corrupted. The

data will be lost.

RAID 1 “Drive Mirroring” Mode:

The two drives show up as a single disk with a size equal to the capacity of a single drive from the array.

RAID 1 copies (or “mirrors”) the data from the rst drive to the second drive. This is useful when reliability

and redundancy are more important than capacity or maximum speed. When one drive fails, it can be

replaced and the data can be rebuilt automatically from the other functioning drive. See Section 2.4 for

more details on the drive replacement and rebuild process.

Warning Changing the RAID mode will destroy the data on the drives. Be sure to back up your data rst!

See Section 3.4 for information on proper backup strategies.

Note Changing the RAID mode for the Mercury Elite Pro Dual requires an active USB or Thunderbolt

connection.

Warning Drives of identical model and capacity are required for RAID 0 and RAID 1. Always maintain a full

and separate backup of your RAID disks, especially RAID 0 disks.
