Led Indicators; Usb Mode - WD My Book Premium ES Edition Schnellinstallationsanleitung

LED Indicators

The LED indicators function differently depending on the interface used (USB or eSATA).

USB Mode

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.

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 from the CD, which must be installed on each system to
which My Book is connected.
Capacity Gauge Activity
The Capacity Gauge is updated automatically upon drive usage. In Windows, you can manually update the
Capacity Gauge by right-clicking the Button Manager icon in the system tray then click outside the pop-up
menu to close it.
eSATA Mode
In eSATA mode, both concentric rings light up when the drive is on and rotate clockwise during drive activity.
Note: Capacity Gauge is not available in eSATA mode.
