3.2.3Standby 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.
