About Your WD Drive
Format and Configuration
This WD device is preformatted as a single Windows NTFS* partition and is
pre-configured for RAID 1 (Mirrored) mode for extra data protection with
instantaneous and automatic data updates. If one drive fails, the dual-drive storage
system will still operate and your data will be preserved. You can replace the failed
drive and rebuild the dual-drive storage system.
This product also supports RAID 0 (Striped) mode for maximum capacity and
accelerated performance. For more information on this product including instructions
on changing the RAID configuration or drive format, see “WD RAID Manager for
Windows” on page 13 or “WD RAID Manager for Mac” on page 17.
* To use this device with a Macintosh computer, you must reformat it to HFS+ (Journaled) or FAT32.
See “WD RAID Manager for Mac” on page 17 for instructions.
LED Indicators (Lights)
The Power/Activity and capacity gauge indicators are represented by a single bar of
four LEDs (lights) on the front panel of the device.
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 up to four sections in an upward vertical direction. Each section
represents approximately 25 percent of drive capacity. Because this drive is
preformatted, the first section is illuminated upon installation.
The capacity gauge is enabled only through installation of WD Drive Manager, which
must be installed on each system to which the device is connected. The capacity
gauge is updated automatically as the drive is used.
