If the drive receives a Set Features command with a mechanism and
mode value of 0000 0001 and the drive supports disabling of IORDY,
then the drive sets its default PIO transfer mode and disables IORDY.

The Idle command and Standby command Sector Count registers are
used to activate the Standby timer. The host can enable the Standby
timer by placing a value in the sector-count register of the Idle command
or Standby command. The value corresponds to a predetermined period
of drive inactivity. The table below lists the values the Seagate drive uses
and their corresponding timeout period.
