having just discovered hdparm command, just got a few questions about it.
hdparm -y /dev/hda
to put the hard drive into standby. after issuing the command, the hard drive did spin down but as soon as it stops, it spins up again as normal.
i then tried
hdparm -Y /dev/hda
to put the hard drive to sleep. similiar thing happened, it went to sleep for a bit and then comes back up again.
why is this? i am guessing that i have some processes that requires constant access to the hard drive. i then did a
but nothing showed up.
can anyone help?
