OWC Mercury Elite Pro Dual mini Chapter 1 - Introduction
1.4 Port View & Cable Connections
➀ ➁ ➂ ➃ ➄ ➅
The OWC Mercury Elite Pro Dual mini comes equipped with multiple
connection interfaces to ensure the maximum computer compatibility
and portability.
FireWire
The Mercury Elite Pro Dual mini features two FireWire 800 ports ➀and one
FireWire 400 port ➁. FireWire 800 provides speeds up to 100 MB/sec and
FireWire 400 provides speeds up to 50 MB/sec.
The use of FireWire does not require any auxiliary power source as each port
carries enough bus power to run the Mercury Elite Pro Dual mini directly
from the computer’s FireWire port.
FireWire also has the ability to daisy-chain or connect multiple FireWire
devices together through one FireWire connection to the computer. OWC
recommends having only one bus-powered device in the chain due to the
limited amount of power a single FireWire port can provide. If a FireWire 400
device is chained with FireWire 800 devices, all devices will throttle down to
FireWire 400 speeds.
USB
The Mercury Elite Pro Dual mini features one USB mini port ➂that provides
speeds up to 60 MB/s.
The USB connection cannot carry enough power for the Mercury Elite Pro
Dual mini, so the use of the optional AC power adapter is needed to con-
nect to the DC In power port ➅.
Please see Section 4.2: Tips for information on purchasing the optional AC
power adapter.

eSATA
The fastest connection on the Mercury Elite Pro Dual mini is the eSATA
connection (4), which provides speeds up to 300 MB/sec.
eSATA is not a powered connection and requires the use of an auxiliary
power source such as the included FireWire 800 to 12V cable or the optional
AC power adapter to connect to the DC In power port ➅. While connected
via eSATA, the Mercury Elite Pro Dual mini can also be powered by utilizing
any of the FireWire 800/400 ports. In this scenario, the Mercury Elite Pro
Dual mini senses both the eSATA and FireWire connections and utilizes the
eSATA for data and the FireWire for power only.
Power Switch
It is recommended to always utilize the On/O power switch ➄to ensure
proper startup and shutdown of the Mercury Elite Pro Dual mini when
connecting and disconnecting from the computer. OWC recommends
attaching the data and power cables before switching the power on. When
disconnecting, make sure to unmount and then turn o the Mercury Elite
Pro Dual mini before disconnecting the data and power cables.
1.5 Front Activity Light View
The Mercury Elite Pro Dual mini features two multi-color LED indicator
lights. The left light corresponds to the left drive, with the right light cor-
responding to the right drive. Each LED light will illuminate red or blue in
color to indicate dierent activities.

2.1 Hard Drive Assembly & Installation (concluded)
➆ Using the included
screws from the plastic bag,
attach the drive mechanisms
to the enclosure through the
rubber grommets using your
Phillips P0 screwdriver.
It is recommended that you
start using 2 screws in each
drive, and not fully tighten
them until all 8 screws are
started into the drive mecha-
nisms.
Once you have installed the
drive mechanisms, simply slide
the inner chassis back through the
outer shell. The outer shell can be
installed in either direction, but
there is a notch on one side that al-
lows the back plate to t properly.
If your case gets turned around
and the back plate does not t cor-
rectly, try reinstalling it from the other side.
Then, place the rear port
cover onto the back of the
enclosure, and attach it using
the 2 Phillips screws and your
Phillips P0 screwdriver you
removed to begin the process.

RAID Conguration Note:
Before proceeding further, look at the next page of this manual, Section 2.2
RAID Conguration and conrm that the enclosure is properly congured
for the RAID type that you wish to use.
Failure to do this step before assembling the enclosure will result in you
having to dissasemble the unit to congure the RAID.

OWC Mercury Elite Pro Dual mini Chapter 2 - System Setup
2.2 RAID Conguration
To adjust the RAID conguration on your OWC Mercury Elite Pro Dual mini,
you need to gain access to the internal bridge board. Visit Section 2.1; Hard
Drive Assembly & Installation to review the basic steps in this procedure.
Once you remove the back
of the OWC Mercury Elite Pro
Dual mini, you will be able to
see the blue DIP Switch block
at the rear of the bridge card,
next to the power switch.
You need to adjust the DIP
switches to change the RAID mode.
Since hard drives have been introduced with capacities greater than 2.2TB,
the industry has worked to resolve known capacity addressing limitations
that date back to the original design of the PC.
These limitations are caused by 32-bit denitions used for partition sizes
and logical block addresses (LBAs) resulting in a maximum addressable
capacity size of 2.199TB.
The most direct way to resolve this issue is to use Long LBAs. However,
Long LBAs are only supported in 64-bit operating systems, like Mac OS X,
Windows 7 and Windows Vista. Users of older operating systems wishing to
use these high-capacity drives will need to limit the drive size to under 2.2TB
to be able to use the storage solution.
To limit the OWC Mercury Elite Pro Dual mini’s maximum drive capacity to
2.2TB, ip the dip switch #1 to the o position. The default position is up, or
ON meaning volumes larger than 2.2TB are able to be created.
MODE SW#1 SW#2 SW#3
SINGLE DRIVES ON OFF OFF
RAID 0 STRIPE ON ON OFF
RAID 1 ON ON ON
SPAN ON OFF ON

OWC Mercury Elite Pro Dual mini Chapter 2 - System Setup
2.2 RAID Conguration (continued)
The OWC Mercury Elite Pro Dual mini is able to utilize the 2 hard drives in
3 dierent RAID modes; Disk Spanning (SPAN), Disk Striping (RAID-0), or
Disk Mirroring (RAID-1). You need to choose the RAID mode that suits your
needs properly.
The OWC Mercury Elite Pro Dual mini also is able to utilize drives in “Single
Drive” mode. This is useful if you have two drives of dierent capacities or
speeds and wish to install them in the enclosure, without the benet of a
RAID.
Disk Spanning
The drives show up as one large single volume. The total size will depend
on the drives installed, you can use drives of dierent capacities. Spanning
is an array (not RAID) that is written sequentially to, across the hard drives.
By itself, it does not provide any performance or redundancy benets.
Disk Striping (RAID 0)
The drives show up as one large (single) volume. It is highly recommended
to use identical hard drives for this RAID method. However, you can utilize
drives of dierent capacity, but realize that the RAID size will be based on
the smallest capacity total of the drives used in the RAID set.
Disk Mirroring (RAID 1)
The drives show up as one volume, but only 50% of the total capacity can
be used. It is highly recommended to use identical hard drives for this RAID
method. However,while you can utilize drives of dierent capacity, the
RAID size will be based on the smallest capacity total of the drives used
in the RAID set. RAID 1 creates an exact copy (or “mirror”) of a set of data
on the second drive. This is useful when reliability and backup are more
important than capacity. When one drive fails, it can be replaced and the
data rebuilt.

2.3 Computer Connections
Please see the previous section 1.4 which details the dierent interface
options available to you with your OWC Mercury Elite Pro Dual mini.
Choose which interface you wish to connect to your computer, connect
that interface and then you need to format the hard drives you just
installed into your new OWC Mercury Elite Pro Dual mini enclosure.
Proceed to the next page to learn how to do that.
Important Note! You can connect multiple drives together using either
of the FireWire connections. No other interface type supports this type of
“daisy chain” connection. If you connect a FireWire 400 device, all devices
connected via the FireWire bus, including FireWire 800 drives, will be
reduced to the maximum speed of FireWire 400.

➆ Type exit and hit enter.
➇ Close the command prompt window.
You may now proceed with formatting the drive.
If you are not installing a brand-new hard drive into your enclosure, it
may have a GUID drive partition already installed on it, especially if it
was originally used with a Macintosh. Unfortunately, this is not readable
by Windows without special software. If you wish to use your storage
solution on a computer running Windows, you will need to repartition
and reformat using the following instructions.
➀ Go to the DOS command prompt by
selecting “Run” from the Start Menu.
➁ Type cmd into the text box, and click
the“OK” button.
➂ Type diskpart and hit enter.
➃ Type list disk and hit enter.
➄ Type select disk xreplacing xwith the number of the disk you want
to reformat. (Typically, you will see an asterisk (*) under “GPT” for the disk
requiring formatting.)
