Hi,
is there a way to set the standby mode for ATA Disks
Under linux hdparm -S seems to work:
-S Set the standby (spindown) timeout for the drive. This value is
used by the drive to determine how long to wait (with no disk
activity) before turning off the spindle motor to save power.
Under such circumstances, the drive may take as long as 30 sec-
onds to respond to a subsequent disk access, though most drives
are much quicker. The encoding of the timeout value is somewhat
peculiar. A value of zero means "off". Values from 1 to 240
specify multiples of 5 seconds, for timeouts from 5 seconds to
20 minutes. Values from 241 to 251 specify from 1 to 11 units
of 30 minutes, for timeouts from 30 minutes to 5.5 hours. A
value of 252 signifies a timeout of 21 minutes, 253 sets a ven-
dor-defined timeout, and 255 is interpreted as 21 minutes plus
15 seconds.
I googled but I did not found anything like this for FreeBSD :/
