About Your WD Drive
LED Indicators
The Power/Activity and Capacity Gauge LEDs are two concentric rings on the front panel of the drive. The outer ring is
the Power/Activity LED and the inner ring is the Capacity Gauge LED.
Power/Activity 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 4).
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.
