When the power save mode is Standby mode, the Idle command causes the device to enter performance Idle mode immediately, and set auto power down timeout parameter(standby timer). And then the timer starts counting down. When the device’s power save mode is already any idle mode, the device keep that mode.
When the Idle mode is entered, 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 host commands immediately.
Output Parameters To The Device
Sector Count Timeout Parameter. If zero, the timeout interval(Standby Timer) is disabled. If other than zero, the timeout interval is set for (Timeout Parameter x5) seconds.
The device will enter Standby mode automatically if the timeout interval expires with no device access from the host. The timeout interval will be reinitialized if there is a device access before the timeout interval expires.
