Before your new Mercury Elite Pro Dual can be put to use, it needs to be formatted. To help
with the formatting process, the OWC Drive Guide formatting utility has been installed on
your Mercury Elite Pro Dual. Follow these steps to use Drive Guide to format your Mercury
Elite Pro Dual for Mac OS X (10.4 and later) or Windows (XP and later):
1. Connect your drive to your computer using the proper cable, then turn on your drive. If
you prefer to use a different formatting utility, do so at this time and skip the rest of these
instructions.
2. Your drive will show up as “OWC HD”. Open your drive to view its contents.
3. Open the “Macintosh Setup” or “Windows Setup” folder, depending on your computer’s
operating system, then double-click the Drive Guide application.

1.6 RAID CONFIGURATION
To change the RAID settings of your Mercury Elite Pro Dual, there are three switches inside
the enclosure that need to be adjusted, circled below in red. You can access the switches by
removing the clip-in fan at the rear of the enclosure.
WARNING: The default RAID configuration for the OWC Mercury Elite Pro Dual is RAID 0.
Configuring a new RAID mode will destroy any data stored on the drives. Back up any
important data before proceeding.

2TB MODE
INDEPENDENT — Each hard drive will appear as a separate volume. You can use different
models and sizes of hard drive with this mode. NOTE: Independent mode is not supported
over eSATA. Only FireWire and USB connections support independent mode.
SPAN — The drives show up as one large single volume. A span is an array (not RAID) in
which data is written sequentially across both hard drives. It combines the capacities of the
two drives, but it does not provide any performance or redundancy benefits.
RAID 0 (STRIPE) — The drives show up as one large single volume. RAID 0 is used when
speed is the primary objective. It is required to use identical hard drives for this RAID level.
RAID 1 (MIRROR) — The drives show up as one volume, but only 50% of the total capacity
can be used. It is required to use identical hard drives for this RAID method. RAID 1 creates an
exact copy (or “mirror”) of a set of data on the second drive. RAID 1 is NOT RECOMMENDED
in the Mercury Elite Pro Dual due to the lack of any indication of a drive failure.
2TB MODE — When switch #1 is in the OFF position, the total capacity of the drives is
limited to a maximum of 2.2TB for compatiblity with older operating systems. NOTE: If setting switch #1 to ON does not initially allow volume sizes to exceed 2.2TB, do the following:
keeping switch #1 in the ON position, change to a different RAID level, then turn on the unit.
Format the new RAID volume, then shut off the unit, change to the desired RAID level (or
independent mode), and turn on the unit.

APPENDIX
2.1 CONNECTIVITY NOTES
• Only one interface (eSATA, FireWire, USB) at a time can be used. When more than one
interface cable is connected, the fastest interface has priority.
• For the safe removal of your drive and to assure 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 Mac OS X 10.4 and above).
2.2 UNMOUNTING DRIVES
To properly unmount any connected drives from your computer, you need to follow a few
simple steps.
For Mac OS X systems:
There are two main methods to umount disks with Mac OS X systems. Either 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”.
For Windows systems:
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.
2.3 TROUBLESHOOTING
Begin your troubleshooting by verifying that the power cable is connected to the Mercury
Elite Pro Dual and to a power source. If the power cable is connected to a power strip, make
sure that the power switch on the strip is turned on.
Then, simply verify that both ends of your cables are properly plugged into the computer
and the Mercury Elite Pro Dual. If the Mercury Elite Pro Dual is still not working properly, try
connecting to another interface such as the USB connection and see if the device works
properly. You can also connect the Mercury Elite Pro Dual to a different computer.
If problems persist, consult our online collection of frequently asked questions (http://
