Table 65 Idle Command (E3h/97h)

When the power save mode is Standby mode, the Idle command causes the device to enter performance

Idle mode immediately, and set auto power down timeout parameter(standby timer). And then the timer

starts counting down. When the device’s power save mode is already any idle mode, the device keep that

mode.

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 ready to respond to host commands immediately.

Output Parameters To The Device

Sector Count

Timeout Parameter. If zero, then the automatic power down sequence is disabled.

If non-zero, then the automatic power down sequence is enabled, and the timeout

interval is shown below:

Value Timeout

---------- -------------------------

0 Timer disabled

1-240 Value * 5

241-251 (Value-240) * 30 minutes

252 21 minutes

253 8 hours

254 Reserved

255 21 minutes 15 seconds

When the automatic power down sequence is enabled, the drive will enter Standby

mode automatically if the timeout interval expires with no drive access from the host.

The timeout interval will be reinitialized if there is a drive access before the timeout

interval expires.
