Power Mode Definitions:
-----------------------
Active	    The drive is spinning and most circuitry is powered on. 
	    The drive is capable of responding to read commands in
	    the shortest possible time. Read/Write heads are positioned
	    over the data area.

Idle	    The drive is spinning., the actuator is parked and powered
	    off, and all other circuitry is powered on. The drive is 
	    capable of responding to read commands within 40 ms.

Read/Write  Data is being read from or written to the drive.

Spin-up	    The drive is spinning up following initial application 
	    of power and has yet not reached full speed. Maximum
	    current draw lasts one second.

Sleep	    This is the lowest power state. The interface becomes 
	    inactive. A software or hardware reset is required to 
	    return the drive to Standby.

Standby	    The spin motor is not spinning. The drive will leave this
	    mode upon receipt of a command that requires disk access.
	    The time-out value for this mode is programmable. The
	    buffer is active to accept write data.
