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?
