About Your WD Drive

Format and Configuration

This WD device is preformatted to HFS+ (Journaled) for compatibility with Macintosh

operating systems and is pre-configured for RAID 0 (Striped) mode for maximum

capacity and accelerated performance.

This product also supports RAID 1 (Mirrored) mode for extra data protection with

instantaneous and automatic data updates. If one drive fails the system will still run

and your data will be preserved. You can replace the failed drive and restore the

system. For more information, including instructions on changing the RAID

configuration or drive format, see “WD RAID Manager for Mac” on page 17 or “WD

RAID Manager for Windows” on page 22.

LED Indicators (Lights)

The Power/Activity and Capacity Gauge indicators are represented by a single bar of

six LEDs (lights) on the front panel of the drive.

Power/Activity LED Behavior

* If this condition occurs, read/write activity will stop and the drive will spin down. Disconnect and

power down My Book. Allow it to cool down for 1-2 hours then reconnect and power up the device.

Capacity Gauge

When the device is turned on, the Capacity Gauge indicates space used on the drive

by illuminating six sections in an upward vertical direction. Each section represents

approximately 17 percent of drive capacity. Because this drive is preformatted, the

first section is illuminated upon installation.

USB and FireWire Mode

The Capacity Gauge is enabled only through installation of WD Drive Manager, which

must be installed on each system to which My Book is connected. The Capacity

Gauge is updated automatically as the drive is used.

eSATA Mode

Capacity Gauge is not available in eSATA mode.
