The Idle Immediate command causes the device to enter Performance Idle mode.
The device is spun up to operating speed. If the device is already spinning, the spin up sequence is not executed.
During Idle mode the device is spinning and ready to respond to the host commands immediately.
The Idle Immediate command will not affect the auto power down time-out parameter.
