To disconnect or unhook your OWC Mercury Rack Pro hard drive,
follow these important steps to properly dismount your drive.
If you wish to disconnect your OWC Mercury Rack Pro storage solution
without shutting down your computer, simply drag the OWC Mercury
Rack Pro drive icon(s) to the trash can on the desktop (or, in the dock
using Mac OS X). Your drive is now safe to power o and unhook.
Realize that you have up to 4 drives to dismount with this 4 bay unit -
make sure all drives are disconnected before powering down.
Share your Mac formatted drive with your PC using MacDrive
(optional purchase)
After installing MacDrive, your HFS+ Macintosh volume will mount as if
the drive were formatted in a native Windows format. MacDrive allows
you to use your OWC Mercury hard drive on either platform without
having to reformat or re-initialize the volume. We highly recommend
this software for anyone that is sharing data in a cross platform
environment.
Cloning drives (exact copies)
If you want to make an exact duplicate of a hard drive, we highly
recommend Mike Bombich’s donationware“Carbon Copy Cloner”. It’s a
great tool! You can nd it on his website at:
http://www.bombich.com/ccc.html
Using with Time Machine (Mac OS X 10.5 “Leopard”)
The OWC Mercury Rack Pro storage solution is fully compatible with
Mac OS X 10.5’s Time Machine as long as you have a hard drive volume
formatted using the Mac OS Extended HFS+ scheme. Follow Time
Machine’s built in instructions to congure.

1. Before installing, make sure that you have reviewed the previous
page and that all necessary cables and parts are present.
2. Please be sure to use the heavy duty power cord that is provided. The
unit is able to be used with 100-240V, 60Hz power and is autoswitching.
3. Any disassembly of the enclosure or modication will void your
warranty. If you are experiencing problems, please contact our technical
support department before opening the enclosure.
4. Hardware Requirements:
• For the best performance, connect the enclosure using the included
1394b cables (FireWire 800). See note below about gaining even more
performance than a single FireWire 800 connection can provide.
• You can also use a USB 2.0 connection (but not at the same time) if you
do not have a FireWire port on your computer.
• You can even use a FireWire 400 to 800 converter cable if you don’t
have a native FireWire 800 port built into your computer.
If you are looking to maximize the performance of this enclosure, it
has the ability to utilize 2 discrete FireWire 800 connections. You can
connect 2 drives to one FireWire 800 interface, for example, the built-in
FireWire 800 connection on your computer, and the other 2 drives to a
PCI/PCI Express FireWire 800 card, doubling the bandwidth available.
5. OS Requirements:
• Mac:
Compatible with all Apple OS Versions 8.5 through 9.2.x; Apple OS X
10.0.3 and higher (including OS X ‘Leopard’ 10.5.x).
• Windows:
Compatible with Microsoft Windows 98SE, ME, 2000, XP; Any OS or
device with standard FireWire or USB support.
IMPORTANT!!
Please read before proceeding with installation
Troubleshooting
Chapter 8
If your OWC Mercury Rack Pro is not functioning properly, begin by
checking some basic possibilities, such as:
• Are all cables tightly attached to the computer and drive?
• Is the power supply plugged in rmly, and is the LED lit on the
power supply brick?
If the above solutions are not working, a full reset of your system may be
in order.
• Performing a set of open rmware reset routines can result in the
memory being properly recognized again. To do this, you will need to
boot your machine into Open rmware.
To boot into Open Firmware, shut down your Mac, then start it up while
holding down the Command, Option, O and F keys. At the Open Firm-
ware screen prompt, enter the following commands (you may want to
write them down on a piece of paper before beginning this process),
pressing the return key after each:
reset-nvram (press return)
set-defaults (press return)
reset-all (press return, your machine will reboot)
For further troubleshooting tips, visit our FAQ section online at:

Please review the following pictures to determine the best way to hook
your new drive solution to your computer.
Power Plug On/O Switch
Insert the power plug and connect to your standard wall outlet. The
internal power supply is autoswitching and you can use it with voltages
ranging from 110V to 220V, 60Hz.
Drives 3 & 4 Drives 1 & 2
1394B
(FW800) USB 2.0 1394B (FW800) USB 2.0
These are the connections you will use to attach the storage solution
to your computer. You will need to decide if you are going to hook the
solution up via FireWire 800 (1394b) - which is the fastest interface this
drive solution uses, or via USB 2.0, or both. If you don’t have a FireWire
800 port you can use a FireWire 400-800 converter cable.
The OWC Mercury Elite Rack Pro has two separate back panel connec-
tions - called bridges - each controlling 2 hard drives. On the following
pages you will see the dierent methods used to connect the drive solu-
tion to your computer.

Removable Trays:
You can purchase extra drive carriers and swap out drive mechanisms,
perfect for o-site backup or archiving.
To remove the drive tray - rst,
make sure the power is turned OFF
on the Mercury Elite Rack Pro - this
is not a “hot swap”procedure.
Start by inserting the included drive
key into the small hole on the right
side of the tray, in the area below
the door.
Push the key in - and it will pop the
door up, allowing you to pull the
tray out of the enclosure.
You can purchase multiple drive
trays and perform a rotation, if you
want to archive data and store it at
another location for safety.

Connection option #1 - Connect to the same FireWire 800 source (built
in FireWire 800 ports, or a PCI/PCIe FireWire 800 card) using two cables -
direct connection for each bridge card.
Connection option #2 - Connect to the same FireWire 800 source (built
in FireWire 800 ports, or a PCI/PCIe FireWire 800 card) via daisy-chaining
the two bridges together, then connect one bridge to the computer.
Connection option #3 - Connect to separate FireWire 800 interfaces
(such as a built in FireWire 800 port, AND a PCI/PCIe FireWire 800 card).
Use the 2 included cables to connect one cable to each of these inter-
faces, doubling the bandwidth.
Of the 3 types of FireWire 800 connection listed above, Connection
option #3 is the fastest.
Step 13 You will see the drive begin to format. This will take up to 5
minutes to complete.
Step 14 The format has completed. You will see it report back as a
healthy partition.
Complete the formatting process for the remaining drives using these
steps. You’re all set!
FireWire 800 (1394B) Connection Options

Page 7 Page 28
Connection option #4 - Connect to the same USB 2.0 source (built in
USB 2.0 ports, or a PCI/PCIe USB 2.0 card) using two cables - direct con-
nection for each bridge card.
Connection option #5 - This option allows you to use both a FireWire
800 and a USB 2.0 connection. Connect one cable from the FireWire 800
ports on either bridge card to the computer, and then connect the USB
2.0 connection on the opposite bridge card to the computer.
This allows you to maximize the performance, of the storage solution,
even though you do not have two identical interfaces.

Ways to NOT hook your storage enclosure to your computer

Page 25 Page 10
Once you have decided on the proper way to connect the OWC Mercury
Rack Pro to your Macintosh, you’re now ready to power the unit on and
begin using it. Do so now.
The OWC Mercury Rack Pro comes from the factory pre congured
one of 3 ways. Please refer to your invoice to verify which method of
conguration you ordered if you do not know already.
The methods are:
JBOD - All 4 hard drives formatted independently, as four individual
hard drive volumes. If you had 4 1TB drives in your OWC Mercury Rack
Pro, you would have 4 1TB volumes mount on your desktop.
Stripe (RAID 0) - Two volumes will mount on your desktop, each made
up of a high-speed RAID-0 Stripe - combining two volumes each. Using
a RAID-0 Stripe format, if you had 4 1TB drives in your OWC Mercury
Rack Pro, you would have 2 2TB volumes mount on your desktop.
RAID 0+1 - This method is a bit dierent than the above two methods as
it uses a piece of software that is included with this bundle - SoftRAID.
SoftRAID combines two Stripe (RAID-0) volumes into a RAID-1 Mirror
- allowing both speed, and full redundancy. If you had 4 1TB drives in
your OWC Mercury Elite 4 Bay RAID Rack using this method, you would
have 1 2TB volume mount on your desktop.
Your solution should be congured properly to work the way that
you ordered it right out of the box. However, if you decide you want
to recongure or change the method you ordered, please see the
following pages to reformat or recongure your RAID. For RAID 0+1
solutions using SoftRAID, please consult the SoftRAID manual on the
included CD with those solutions.
