About Your WD Storage Device

Welcome to your My Book® Thunderbolt™ Duo dual-drive storage device, featuring
revolutionary Thunderbolt technology that sets new standards for data transfer speeds
and workflow flexibility in high-capacity storage.

This chapter includes the following topics:

Optional Accessories
Operating System Compatibility

Handling Precautions

Features

Move data at unprecedented speeds—Do more work in less time with ground­breaking data transfer speeds using Thunderbolt technology. Your My Book Thunderbolt
Duo dual-drive storage 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 ports to daisy chain up to six
Thunderbolt storage devices to achieve maximum workflow efficiency and productivity.

High-speed multitasking—The revolutionary bidirectional Thunderbolt technology
delivers unmatched speed for multitasking projects.

Super-fast external boot capability—For information about using your My Book
Thunderbolt Duo as an external boot device using Mac OS X 10.6.8 or later, see the
Apple Support article at http://support.apple.com/kb/HT4718 or http://

docs.info.apple.com/article.html?path=Mac/10.7/en/mchlp1034.html.

User serviceable—When you need to replace a drive, just open the case and do it
yourself. No tools are needed.

Operating System Compatibility

Your My Book Thunderbolt Duo dual-drive storage device and WD Drive Utilities
software are compatible with the following Mac OS X

10.6.8 or later operating systems

on Thunderbolt technology-enabled computers:

• Snow Leopard

™

• Lion

Compatibility can vary, depending on hardware configuration and operating system.

For highest performance and reliability, always install the latest software update. Go to
the Apple menu and select Software Update.

Disk Drive Formats

Your My Book Thunderbolt Duo dual-drive storage device is initially formatted with
HFS+J partitions and configured as a striped RAID disk array (RAID 0).

In the RAID configurations, both drives are formatted with a single HFS+J partition for
Mac OS X operating systems. In the JBOD configuration, each drive can be reformatted
as either:

• HFS+J for Mac computers

• exFAT for running Windows operating systems on Mac computers

Note: Older Windows operating systems might need a patch from Microsoft to recognize

the exFAT format. (See http://support.microsoft.com/?kbid=955704.)

Physical Description

As shown in Figure 2, the My Book Thunderbolt Duo dual-drive storage device has:

• A power/activity LED indicator on the front

• The power connector, Thunderbolt ports, and a security slot on the back

Thunderbolt Ports

As shown in Figure 2 on page 3, the My Book Thunderbolt Duo dual-drive storage
device has two dual-channel Thunderbolt ports that provide a fast, flexible interface for:

• Performance—Thunderbolt technology delivers unprecedented data transfer
rates thanks to its revolutionary bidirectional I/O throughput. Each Thunderbolt
port provides two bidirectional channels, each with theoretically up to 10 Gb/s of
bandwidth.

• Simplicity—Thunderbolt technology supports daisy chaining multiple devices
through a single Thunderbolt connector so you can multitask at Thunderbolt
technology speed without having to use a switch or hub. This reduces the
hardware clutter and increases productivity.

• Flexibility—Connect additional Thunderbolt technology-enabled external hard
drives, media players, HD displays, media capture and editing systems and more
through a single connector.

Note: Your My Book Thunderbolt Duo device must be connected to a Mac computer that

supports Thunderbolt technology. For information about cables that support
Thunderbolt technology, visit
