Ok should this solve my problem ? it still does not work.
Do you know if IDLE time is software or hardware ? I mean,  is my HDD 
"forgetting" to tell to my system that it is idle since 5 seconds and 
needs a hdparm -y ?
Or is it able to decide by itself to go into standby mode when IDLE ?
Thank you.
