Features
Move data at unprecedented speeds—Do more work in less time with groundbreaking data transfer speeds using Thunderbolt technology. Your My Book Pro device
provides a fast way to get information to and from your external drives.
Multiple dual-drive storage configurations—Select RAID or Individual Drives modes:
RAID 0 (Striped mode) for maximum capacity and accelerated performance.
RAID 1 (Mirrored mode) for double-safe data protection by automatically creating a
second copy of your data. One of the drives stores your data and the other drive
saves a second copy. If either drive fails, your data is protected because it is
duplicated on the other drive.
JBOD (Individual Drives mode) for using the two drives independently, and not
configured into a RAID array.
Enhance workflow efficiency—Use the two Thunderbolt 2 ports to daisy chain up to
six Thunderbolt storage devices to achieve maximum workflow efficiency and
productivity.
Super-fast external boot capability—For information about using your My Book Pro
device as an external boot device using Mac OS X 10.7 or later, see the Apple Support
article at http://support.apple.com/kb/HT4718 or

USER MANUAL
Checking Device Health
The WD Drive Utilities software provides three diagnostic tools to help make sure that
your drive is performing well. Run the following tests if you are concerned that your drive
is not operating properly:
Drive status check
The drive status check is a failure-prediction function that continuously monitors key
internal performance attributes of the device drives. A detected increase in drive
temperature, noise, or read/write errors, for example, can provide an indication that
the drive is approaching a serious failure condition. With advanced warning, you
could take precautionary measures, like moving your data to another device, before
a failure occurs.
The result of a drive status check is a pass or fail evaluation of the drive’s condition.
Quick drive test

Your device drives have a built-in Data Lifeguard
drive for error conditions. The quick drive test checks the drive for major
performance problems.
diagnostic utility that tests the
The result of a quick drive test is a pass or fail evaluation of the drive’s condition.
Complete drive test
The most comprehensive drive diagnostic is the complete drive test. It tests every
sector for error conditions and inserts bad sector markers as required.
The best time to run the drive diagnostics and status checks is on a regular basis, before
you encounter any problems with your drive. And, because they are so fast, running the
drive status check and the quick drive test provides a high level of assurance with
minimal inconvenience. Then, run all three whenever you encounter disk error conditions
when writing or accessing files.
1. Click Go > Applications > WD Drive Utilities to display the WD Drive Utilities
screen, Diagnose dialog (see Figure 4 on page 12).
2. If you have more than one supported device connected to your computer, select the
one that you want to check.

Obtaining Service
WD values your business and always attempts to provide you the very best of service. If
this Product requires maintenance, either contact the dealer from whom you originally
purchased the Product or visit our product support website at
http://support.wd.com/warranty/policy.asp for information on how to obtain service or a
Return Material Authorization (RMA). If it is determined that the Product may be
defective, you will be given an RMA number and instructions for Product return. An
unauthorized return (i.e., one for which an RMA number has not been issued) will be
returned to you at your expense. Authorized returns must be shipped in an approved
shipping container, prepaid and insured, to the address provided on your return
paperwork. Your original box and packaging materials should be kept for storing or
shipping your WD product. To conclusively establish the period of warranty, check the
warranty expiration (serial number required) via
http://support.wd.com/warranty/policy.asp. WD shall have no liability for lost data
regardless of the cause, recovery of lost data, or data contained in any Product placed in
its possession.
Limited Warranty
WD warrants that the Product, in the course of its normal use, will for the term defined
below, be free from defects in material and workmanship and will conform to WD’s
specification therefor. The term of your limited warranty depends on the country in which
your Product was purchased. The term of your limited warranty is for 2 years in the
North, South and Central America region, 2 years in the Europe, the Middle East and
Africa region, and 3 years in the Asia Pacific region, unless otherwise required by law.
The term of your limited warranty period shall commence on the purchase date
appearing on your purchase receipt. WD shall have no liability for any Product returned if
WD determines that the Product was stolen from WD, is counterfeit or fake, or that the
asserted defect a) is not present, b) cannot reasonably be rectified because of damage
occurring before WD receives the Product, or c) is attributable to misuse, improper
installation, alteration (including removing or obliterating labels and opening or removing
external enclosures, unless the product is on the list of limited user-serviceable products
and the specific alteration is within the scope of the applicable instructions, as found at
http://support.wd.com/warranty/policy.asp), accident or mishandling while in the
possession of someone other than WD. Subject to the limitations specified above, your
sole and exclusive warranty shall be, during the period of warranty specified above and
at WD’s option, the repair or replacement of the Product.
The foregoing limited warranty is WD’s sole warranty and is applicable only to products
sold as new. The remedies provided herein are in lieu of a) any and all other remedies
and warranties, whether expressed, implied or statutory, including but not limited to, any
implied warranty of merchantability or fitness for a particular purpose, and b) any and all
obligations and liabilities of WD for damages including, but not limited to accidental,
consequential, or special damages, or any financial loss, lost profits or expenses, or lost
data arising out of or in connection with the purchase, use, or performance of the
Product, even if WD has been advised of the possibility of such damages. In the United
States, some states do not allow exclusion or limitations of incidental or consequential
damages, so the limitations above may not apply to you. This warranty gives you
specific legal rights, and you may also have other rights which vary from state to state.

originally purchased the Product. If you are unable to contact the dealer from whom you
originally purchased the Product, please visit our product support website at

Authorization (RMA). If it is determined that the Product may be defective, you will be
given an RMA number and instructions for Product return. An unauthorized return (i.e.,
one for which an RMA number has not been issued) will be returned to you at your
expense. Authorized returns must be shipped in an approved shipping container,
prepaid and insured, to the address provided with your RMA number. If following receipt
of a qualifying claim under this warranty, WD or the dealer from whom you originally
purchased the Product determines that your claim is valid, WD or such dealer shall, at its
discretion, either repair or replace the Product with an equivalent or better Product or
refund the cost of the Product to you. You are responsible for any expenses associated
with a claim under this warranty. The benefits provided to you under this warranty are in

and Consumer Act or the New Zealand Consumer Guarantees Act.
