12.7.6 S.M.A.R.T operation with power management modes
The device saves attribute values automatically on every head unload timing except the emergency
unload, even if the attribute auto save feature is not enabled. The head unload is done not only by
Standby, Standby Immediate, or Sleep command, but also by the automatic power saving functions like
ABLE-3 or Standby timer. So basically it is not necessary for a host system to enable the attribute auto
save feature, when it utilizes the power management. If the attribute auto save feature is enabled,
attribute values will be saved after 30minutes passed since the last saving, besides above condition.
