Introduction
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.
- Booting in RAID 0, RAID 1, and SPAN mode are supported without limitation.
- The following limitations apply when booting in Independent mode:
- Only the disk connected to Port 2 is bootable when both drives are installed.
- If only one drive is installed, the disk will boot regardless of which port it is connected to. See
Section 2.2 for more information on ports and drive connections.
- 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. Performance is identical on all
USB ports on the USB-C Dock.
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
- 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).
- A message will appear, detailing the devices that the “Eject” icon controls, i.e., “Safely remove...”
Click on this prompt.

Introduction
INSTALLATION
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.
2.1 Assembly
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. IMPORTANT: opening an
enclosure with pre-installed drives will VOID the warranty. You may replace the drives after the expiration of the
original warranty. 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.

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.

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.

2.2 RAID Settings
Warning
Note
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.
Changing the RAID mode for the Mercury Elite Pro Dual mini requires an active USB connection.
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.
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.
2.3 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
OWC Mercury Elite Pro Dual mini
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.

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 compensation of any kind or recovery of the data.
