1.6 Usage Notes
•Identical drives (model, capacity, firmware) are required for RAID 0 and RAID 1 configurations.
•When operating in Independent Mode, if only one drive is installed, either port can be used and there is
no boot limitation. However if two drives are installed, only the drive connected to Port 2 can be used
as a boot disk. The Startup Disk screen in OS X System Preferences will show both drives, however
when the Option-boot screen appears, the drive connected to Port 1 will not be visible.
•If your USB-C host supports the USB Power Delivery 2.0 specification, it can bus-power the Mercury
Elite Pro Dual mini. Other USB hosts may be able to bus-power this device as well. If you find that your
chosen host does not bus-power the device, please use the included power supply.
•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 off the Mercury Elite Pro Dual mini.
You can use the methods described below to safely unmount your disk(s).
•Currently the Mercury Elite Pro Dual mini is not compatible with the USB-C port on the OWC USB-C
Dock. Please connect to one of the USB Standard-A ports instead.
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.

DEVICE SETUP
2.1 Quick Start
Follow the steps below to use the OWC Drive Guide utility to format your Mercury Elite Pro Dual mini for Mac OS
X or Windows. 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 mini and plug it into to your computer using one of the included data
cables. 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: these assembly instructions are written for users who purchased the Mercury Elite Pro Dual mini 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 mini 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 13 in that case and work backwards.
1. Remove the Elite Pro Dual mini from its packaging,
set it on your work surface and remove the two
screws attached to the rear cover (highlighted
at right). Note: once you remove the screws, the
back plate will fall out of the enclosure as shown
in the next step.
2. Grasp the front grill and gently pull the inner
chassis from the outer enclosure, as shown at
right.

DEVICE SETUP
3. Pull the inner chassis the rest of the way out and
remove the screw packet.
4. Hold the first SATA drive at a slight angle and line
up the SATA connectors on the drive with the
SATA ports on the printed circuit board, as shown
at right. Once aligned, slide the drive into the
ports just enough so the drive can be set down
flat inside the inner chassis, as shown in Step 5.
5. Use your thumbs to gently press the drive forward,
until it is fully connected to the SATA ports on the
printed circuit board. Repeat Steps 4 and 5 with
the second SATA drive.
6. Flip the outer enclosure so that its rubber feet are
facing up and oriented as shown above.

DEVICE SETUP
7. Turn the inner chassis over and set it on the outer
enclosure so that the drives rest on two of the feet
and slightly overhang the edge of the enclosure,
as shown at right.
8. Take the larger screws from the packet and insert
them in the row of screw holes at the back of the
chassis, then partially tighten them.
9. Take the rest of the large screws and insert them
in the remaining screw holes, partially tightening
them.
10. Turn the inner chassis over and visually inspect
the two drives to ensure they are properly aligned
before moving on to the next step.

11. Turn the inner chassis over and set it on the outer
case as before, then fully tighten all eight screws
from Steps 8 and 9.
12. Set the inner chassis aside, turn the outer
enclosure over and orient it as shown at right.
Next, align the guides on the chassis with the
guide rails in the enclosure. Note that the rails
extend to the edge on only one side of the
enclosure. Slide the chassis in until the front grill
contacts the enclosure.
13. Pick up the rear cover, carefully align the cutouts
with the ports on the back of the inner chassis,
the re-affix the two screws.
This completes the assembly process.

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.
Note
Changing the RAID mode for the Mercury Elite Pro Dual mini requires an active USB connection.
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. To
change the RAID mode, follow the simple steps below. When adjusting the
RAID mode, turn the dial so that the arrow is pointing at the desired setting.
A small flathead screwdriver works the best to adjust the dial. Each time the
arrow is aligned with a new mode, you will feel a slight click.
When starting from a powered-on state, first 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-off state, rotate the dial on the back of the enclosure to the desired
RAID mode, then power on the Mercury Elite Pro Dual mini 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.
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.
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 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.
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 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.

DEVICE SETUP
Span Mode:
Both drives show up as a single large disk, but one which functions differently than RAID 0. The total size
will depend on the drives installed; unlike RAID 0 or RAID 1 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.
2.4 Drive Failure
If one of the drives fails, the corresponding drive LED will turn solid red. If the Mercury Elite Pro Dual mini was
configured as a RAID 0 or Span, the data on the array is lost and the disk 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 retrieve the data from
the other drive. 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 Mercury Elite Pro Dual mini 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 array is rebuilt with a new drive. If the enclosure
was purchased with drives and it is still under warranty, contact OWC technical support for assistance
(see Section 3.5). 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 LED 1 is solid red, the failed drive is the one connected to the drive shown on the right in Section
2.2 Step 10. If the LED 2 is solid red, the failed drive is the one connected to the drive shown on the left in
Section 2.2 Step 10.
Once the drive has been replaced, if the Mercury Elite Pro Dual mini is configured as a RAID 1, the array will
automatically begin to rebuild when the enclosure is powered 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 new drive
will blink blue, then blink red.
If possible, leave the Mercury Elite Pro Dual mini powered on during the entire rebuild process; if power is
interrupted (or the computer sleeps), the unit will continue rebuilding automatically when power is restored.
Once the rebuild process is complete, both LEDs will display as a solid blue. See Section 1.4 for more
information on the behavior of the LEDs.
Note
The Mercury Elite Pro Dual mini needs an active data signal to remain powered on. If it is
disconnected from the computer, or if the computer goes to sleep or turns off, the device will
power 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.

Mac or Windows, go to: www.owcdigital.com/format
3.2 Troubleshooting
If you are powering the Mercury Elite Pro Dual mini with the included power supply, begin by verifying that the
power cable is properly connected to the device and to the power outlet. 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 Mercury Elite Pro Dual mini. If you are still having trouble, try
connecting the other USB cable that was included (or a different cable of the same type as the one you originally
used) to see if the drive works properly. If this does not resolve the issue, you can also connect the device to a
different computer.
If one of the drive LEDs is solid red, then that drive is either not properly connected, is missing, or has failed. If
you purchased the Mercury Elite Pro Dual mini as an empty enclosure, or, if the enclosure shipped with drives
installed but is past the three year warranty period, unmount the disk from the OS, power off, then check the
drive connections on the inner chassis. See Section 2.4 for steps on how to replace a drive (including how to
rebuild a RAID 1 array) if you are sure the drive has failed. If the Mercury Elite Pro Dual mini is not past the three
year warranty period, or if you need assistance for other reasons, Section 3.5 provides information for contacting
technical support.
3.3 About Data Backup
To ensure that your files are protected and to prevent data loss, we strongly suggest that you keep two copies of
your data: one copy on your Mercury Elite Pro Dual mini and a second copy on either your internal drive or another
storage medium, such as an optical backup, or on another external storage unit. Any data loss or corruption
while using the Mercury Elite Pro Dual mini is the sole responsibility of the user, and under no circumstances may
OWC, its parents, partners, affiliates, officers, employees, or agents be held liable for loss of the use of data including
