The Power/Activity and Capacity Gauge indicators are represented by a single bar of
six LEDs (lights) on the front panel of the drive.

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