The Standby command causes the device to enter the Standby Mode immediately and to set the auto power down 
time-out parameter (standby timer).

When this command is issued, the device confirms the completion of the cached write commands before returning 
the command completion. Then the device is spun down. If the device is already spun down, the spin down 
sequence is not executed.

During the Standby mode the device will respond to commands, however there will be a delay while waiting for 
the spindle to reach operating speed.

The timer starts counting down when the device returns to Idle mode.

Sector Count   The Time-out Parameter. It is is zero, the time-out interval (Standby Timer) is disabled. If it is other 

than zero the time-out interval is set for (Time-out Parameter × 5) seconds.

When the automatic power down sequence is enabled, the device will enter the Standby mode 
automatically if the time-out interval expires with no device access from the host. The time-out 
interval will be reinitialized if there is a device access before the time-out interval expires.
