About Your WD Drive
LED Indicators
The Power/Activity and Capacity Gauge LEDs are two concentric rings on the front

Capacity Gauge LED.

Capacity Gauge
The Capacity Gauge (inner LED) consists of six sections which illuminate in a clockwise
direction to indicate space used on the drive. Each section represents approximately 17
percent of disk space. Because this drive is preformatted and contains software and
utilities, the first section is illuminated upon installation. The Capacity Gauge is enabled
only through installation of its driver, which must be installed on each system to which
My Book is connected.
For Mac, you must install the Button Manager and driver (see "Installing the Drive" on
page 3). For Windows, the autorun menu appears only on first installation of the drive
when utilities are installed automatically. If AutoPlay is disabled on your computer or if
you are connecting My Book to another computer, you must install utilities manually. Go
to the desktop. Double-click My Computer, the My Book folder, the
WD_Windows_Tools folder, and Setup.exe.
Capacity Gauge Activity
The Capacity Gauge is updated automatically upon drive usage. For Windows, the
Capacity Gauge is updated only on system or drive restart. To update the Capacity
Gauge without restarting, simply right-click the Button Manager icon in the system tray
then click outside the pop-up menu to close it.
Choosing an Interface
My Book Pro Edition is equipped with three interfaces: FireWire 800, FireWire 400,
and USB 2.0. Choose the best interface depending on your system configuration.
FireWire 800: FireWire 800 has a maximum data transfer rate of 800 Mb/s. It is not
backward-compatible with FireWire 400.
FireWire 400: FireWire 400 supports data transfer rates up to 400 Mb/s.
USB 2.0: For most PCs, the standard interface is USB. Hi-Speed USB (USB 2.0)
supports data transfer rates up to 480 Mb/s. USB 2.0 is backward-compatible with
USB 1.1. If you connect to a USB 1.1 device, data is transferred at USB 1.1 speed (up
to 1.5 Mb/s).
