I used ataidle -P 0 /dev/ad0 to disable it and it works. When I saw there was a atacontrol command for this, I tried it, so I removed ataidle and I tried : markand@Melon ~ $ sudo atacontrol spindown ad0 0 markand@Melon ~ $ sudo atacontrol spindown ad0 ad0: idle spin down disabled But I can still hear the noise every 10 seconds, I think atacontrol does not totally close the APM feature of the device. Do you have any clue? Cheers, -- David Demelier
