3.2.3 Standby timer timeout period

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 drives use

and their corresponding timeout period.
