ok i tried 'hdparm -y /dev/sda' and though i can hear a little noise as if
the disk is in sleep
mode after a while (5 secs) it makes a noise as though it is spinning up
again...also
'hdparm -C /dev/sda' shows the disk active/idle...i also tried with 'hdparm
-S12 /dev/sda'
but couldn't tell whether it is working or not...how can i make sure it
actually works?
