YES IT DOES WORK !
(i apoligize for what I previously said)

But I'd like to undersand why :)

So ... Do you know how noflushd operates ?
Seems like it  works this way :
1) monitor IO stats
2) If no IO for a sufficient amount of time, issues a hdparm -y command.
Basicaly, noflushd could work on a drive on which hdparm -S would not work,
but hdparm -y would ... true ?


While hdparm -S command write directly in the HDD apm registers.
Can anyone confirm that ?

Thank you :)
