￿￿￿￿￿￿￿￿￿2QYGTThe￿%QPFKVKQPPower Condition￿2CIG￿￿￿#JPage￿controls disk drive Power Management functions. Power Management provides three sub-states of UNIT READY:

ACTIVE: This is the state of highest power consumption for the disk drive. A media access command is acted upon immediately by the drive.

IDLE: This is a state of lower power consumption for the disk drive. A media access command is acted upon after a delay of approximately one second.

STANDBY: This is the state of lowest power consumption for the disk drive. A media access command is delayed by approximately 10 seconds

before being acted upon.

Note that in all three sub-states, the drive remains READY.
