Format and Configuration
My Book Premium Edition II is preformatted for Windows (NTFS) and is
pre-configured for RAID 0 (Striped) mode for maximum capacity and accelerated
performance. This product also supports RAID 1 (Mirrored) mode for data protection
with instantaneous and automatic data updates. For more information on this product
including instructions on changing the RAID configuration or drive format, see section
4 for Windows or section 5 for Mac.
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 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.
