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	21 minutes 10 seconds
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.
