hdparm -y question.....


hi there:

having just discovered hdparm command, just got a few questions about it.

i tried

PHP Code:
hdparm -/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

PHP Code:
hdparm -/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

PHP Code:
ps -
but nothing showed up.

can anyone help?

cheers

CHUN

If your swap partition is on hda then the disk gets a lot of accesses all the time, effectively keeping the disk from going to standby.
