Idle command (E3h/97h) The Idle command causes the device to enter Idle mode immediately and sets the auto power down time-out Parameter (standby timer). At the set of the auto power down time-out Parameter (standby timer) the point timer starts counting down. When the Idle mode is entered, the device is spun up to operating speed. If the device is already spinning, the spin up sequence is not executed. During Idle mode the device is spinning and is ready to respond to host commands immediately. Output Parameters To The Device Sector Count This indicates the Time-out Parameter. If the time-out Parameter is equal to zero the time-out interval (Standby Timer) is NOT disabled and the time-out interval is set automatically for 109 minutes. If the time-out Parameter is other than zero, the time-out interval is set for (Time-out Parameter × 5) seconds. The device will enter 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. Travelstar 32GH/30GT/20GN hard disk drive specifications 124

Figure 82. Idle command (E3h/97h)
The Idle command causes the device to enter Idle mode immediately and sets the auto power down
time-out Parameter (standby timer). At the set of the auto power down time-out Parameter (standby timer)
the point timer starts counting down.
When the Idle mode is entered, the device is spun up to operating speed. If the device is already spinning,
the spin up sequence is not executed.
During Idle mode the device is spinning and is ready to respond to host commands immediately.
Output Parameters To The Device
Sector Count
This indicates the Time-out Parameter. If the time-out Parameter is equal to zero
the time-out interval (Standby Timer) is NOT disabled and the time-out interval is
set automatically for 109 minutes. If the time-out Parameter is other than zero, the
time-out interval is set for (Time-out Parameter × 5) seconds.
The device will enter 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.
