Device Overview

Low Power Idle:	The head is unloaded from disk.
	The spindle motor rotates.
Standby:	The spindle motor stops.

In APM Mode-1, which is the APM default mode, the operation status shifts till it finally reaches "Low Power Idle."

Table 1.7 Advanced Power Management

	APM Mode	Active Idle	Low Power Idle	Standby
	APM Mode	(VCM Lock)	(Unload)	(Spin Off)
		(VCM Lock)	(Unload)	(Spin Off)

	Mode-0	3-4 sec	15 min.	N/A

	Mode-1	3-4 sec	10-40 sec	N/A

	Mode-2	3-4 sec	10-40 sec	N/A

When the maximum time that the HDD is waiting for commands has been exceeded:

Mode-0: Mode shifts from Active condition to Active Idle in 3-4 seconds, and to Low Power Idle in 15 minutes.

Mode-1: Mode shifts from Active condition to Active Idle in 3-4 seconds and to Low Power Idle in 10-40 seconds.

Mode-2: Mode shifts from Active condition to Active Idle in 3-4 seconds and to Low Power Idle in 10-40 seconds.

Remark:

The default values of these settings are reflected in the WORD 91 values of the IDENTIFY DEVICE command. Also, the APM mode is initialized to Mode-1 (default value) at power-off.

The above mentioned is time until shifting to each power mode based on point that the drive becomes a command waiting state.
