INTRODUCTION

NOTES:

• Only one interface (USB 3.0 or FireWire 800) at a time can be used.

• For the safe removal of your drive and to ensure that no data is lost, always eject or unmount the drive from your operating system before powering off.

• In order for the computer to access volumes larger than 2TB, the operating system needs to support large volumes (e.g., Windows Vista or OS X 10.4 and above).

• If the power is turned on but there is no active data connection, or if the computer is sleeping, both drive LEDs will display as

solid red.

If this happens when the drive is not sleeping and there is a cable connection present, check both ends of the data cable to make sure it is securely connected to the Elite Pro Dual and the computer.

DEVICE SETUP

2.1 QUICK START

Follow the steps below to use the OWC Drive Guide utility to format your Elite Pro Dual for

Mac (OS X 10.4 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 Elite Pro Dual and plug it into to your computer using the proper data cable.

If you prefer to use a different 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 finished the drive is ready to use.

2.2 ASSEMBLY

NOTE: The following assembly instructions are written for users who purchased the Elite

Pro Dual as an empty enclosure. The instructions show how to open the Elite Pro Dual in order to change the RAID settings and install drives. If you purchased the Elite Pro Dual

with drives already installed, opening the Elite Pro Dual 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.

1. Remove the Elite Pro Dual from the retail box and the protective plastic bag. Set the Elite

Pro Dual on its side and look at the bottom of the enclosure. Use a Phillips screwdriver to remove the two screws, as circled below in red.

DEVICE SETUP

2. Once the two screws have been removed, slide the inner chassis out the front of the outer enclosure, as shown below. Start by pushing on the rear of the inner chassis, then when you are able to grip the front grill of the inner chassis, pull it the rest of the way.

3. When removed from the outer enclosure, the inner chassis will appear as shown below.

There will also be a packet of screws inside (not shown). Remove this packet and use the screws as directed in subsequent assembly steps.

DEVICE SETUP

4. Install the first hard drive (Drive 1), as shown below. Slide the SATA connector on the hard drive into the black SATA connector (circled in red). Make sure the drive is firmly seated in the black SATA connector before proceeding. NOTE: In this picture, the red SATA cable used to connect the second hard drive has been removed. This was done to provide a better image of the drive installation only. Do not remove any cabling from the Elite Pro Dual.

5. Install the second hard drive (Drive 2), as shown below. Insert the SATA connector from the red cable into the SATA connector on the hard drive. Make sure the SATA connectors are seated firmly before continuing. NOTE: Make sure that the flat red cable is twisted as shown (below-right) in order to avoid interfering with the exhaust fan.

DEVICE SETUP

6. Using eight of the larger screws from the packet you removed from the inner chassis, fasten the inner chassis to the hard drives. There are four screw holes on each side of the inner chassis, circled below in red.

7. Slide the inner chassis back into the outer enclosure. Note that while the inner chassis can slide into both sides of the outer enclosure, there is only one correct way that will allow the screw holes to line up correctly.

To determine the correct orientation of the outer enclosure with the inner chassis, turn the outer enclosure on its side and look at the bottom. As shown below, 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.

2.3 RAID SETTINGS

!

WARNING: Changing the RAID mode will destroy the data on the drives. Be sure to back up your data first! See section 3.4 for information on proper backup strategies.

!

2.3.1 Changing the RAID Mode

The RAID mode is controlled by a dial on the rear of the unit, as shown at left. The dial has four positions, each labeled with a different

RAID mode. In order 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 flathead screwdriver works the best to adjust the dial.

When starting from a power on state, rotate the dial on the back of the enclosure to the desired RAID mode, then unmount the drive and power off the Elite Pro Dual. Next power on the Elite Pro Dual. The LEDs on the front will blink for a brief time; once the blinking stops the drive is ready to use.

When starting from a power off state, rotate the dial on the back of the enclosure to the desired RAID mode, then power on the Elite Pro Dual. The LEDs on the front will blink for a brief time; once the blinking stops the drive is ready to use. NOTE: changing the RAID mode for the Mercury Elite Pro Dual requires an active USB or FireWire connection.

See Section 2.3.2 - “RAID Modes” for more information on each RAID mode that can be used, and how it differs from the others.

DEVICE SETUP

2.3.2 RAID Modes

RAID 0 “Drive Striping” Mode:

The two drives show up as a single large volume 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 files 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. Always maintain a full and separate backup of your RAID 0 data!

RAID 1 “Drive Mirroring” Mode:

The two drives show up as a single volume with a size equal to the capacity of a single drive from the array. RAID 1 copies (or “mirrors”) the data from the first 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.

Span Mode:

Both drives show up as a single large volume, but one which functions differently than

RAID 0. The total size will depend on the drives installed; unlike RAID 0 you can use drives of different capacities. A Span is an array (but not a RAID) in which the data is written sequentially across the drives. When one drive becomes full, subsequent data is written to the second drive. This combines the capacities of the drives, but it does not provide any performance or data redundancy benefits.

Independent Drive Mode

Each drive will appear individually without being combined. If you are using drives of differing capacity and model, or if you are using only one drive, this is the mode to use.

NOTE: Drives of identical model and capacity are required for RAID 0 and RAID 1.

DEVICE SETUP

2.4 DRIVE FAILURE

In the event that one of the drives fails, the corresponding drive LED will turn solid red. If the Mercury Elite Pro Dual was configured as a RAID 0 or Span, the data on the array is lost and the volume is no longer usable. In a span, only the data stored on the failed drive is lost, although data recovery software will be required to recover the data from the other drive in the Span. If the drives were configured independently, then the data on the drive that did not fail will remain intact.

2.4.1 Replacing Drives

If the Elite Pro Dual is set up as a RAID 1, a drive that has failed can be replaced. The data will remain accessible via the functioning drive, until the RAID 1 array is rebuilt with a new drive. If the Elite Pro Dual was purchased with drives already installed and it is still under warranty, see Section 3.6 to contact OWC technical support and arrange for replacement. If the unit is outside its warranty or was purchased without drives, follow the assembly instructions in Section 2.2 to access and replace the failed drive.

If the Drive 1 LED is solid red, the failed drive is the one on the bottom, connected directly to the black SATA connector on the circuit board (see Section 2.2, step 4). If the

Drive 2 LED is solid red, the failed drive is the one on the top, connected using a SATA cable (see Section 2.2, step 5).

IMPORTANT:

a failed drive must be replaced with a drive of identical model and capacity.

Once the drive has been replaced, if the Elite Pro Dual is configured as a RAID 1, the array will automatically begin the rebuild process when it is turned on. This process may take several hours to more than a day, based on the capacity of the drives. During the rebuild process, the LED for the drive being rebuilt (Drive 1 or Drive 2) will

blink green

, and the rebuild LED will

blink green

.

It is recommended to leave the Elite Pro Dual turned on during the entire rebuild process, but if power is interrupted (or the computer sleeps), the unit will continue rebuilding automatically when power is restored. Once the rebuild process is complete, the rebuild

LED will turn off and the LED for the rebuilt drive will resume normal activity. See Section

1.4 for more information on the behavior of the LEDs on the front of the Elite Pro Dual.

NOTE: The Mercury Elite Pro Dual needs an active data signal to remain on. If it is

disconnected from the computer, or if the computer goes to sleep or turns off, the device will turn off. To minimize the total rebuild time, it is recommended to keep the device connected to the computer (with the computer powered on), and disable any hard drive sleep settings on the computer for the duration of the rebuild process.

3.1 FORMATTING

For additional formatting information, including instructions on how to format your Elite Pro

Dual for Mac or Windows, go to: www.owcdigital.com/format

3.2 UNMOUNTING DISKS

To properly unmount any disks at the operating system level, you can follow these steps:

OS X:

There are several methods to unmount disks when using OS X systems. You can 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”. You can also eject the disk in the sidebar of a Finder window, 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 Elite Pro Dual from the computer.

3.3 TROUBLESHOOTING

Begin your troubleshooting by verifying that the power cable is connected to the Elite Pro

Dual and to a power source. If the power cable is connected to a power strip, make sure that the power strip switch is in the “on” position. Next, verify that both ends of the data cable are properly plugged into the computer and the Elite Pro Dual.

If you are still having trouble, try connecting a different type of data cable and see if the Elite

Pro Dual works properly; you can also connect the device to a different computer or use different cables of the same type. Sometimes the cables themselves can have flaws.

If one of the drive LEDs (Drive 1 or Drive 2) is solid red, then that drive has failed. See Section

2.4 for instructions on how to proceed. If the Elite Pro Dual is configured as a RAID 1 and the

rebuild LED is blinking, simply wait for the rebuild process to complete. If the rebuild LED is still blinking after more than 48 hours, contact tech support for assistance.

If problems persist, Section 3.6 provides information for contacting technical support.
