Ma question c’est est-ce normal d’avoir pas de ptit étoile devant “DMA Setup Auto-Activate optimization” et “Automatic Acoustic Management feature set” ? d’autant que “Recommended acoustic management value: 128, current value: 254” qu’est-ce que c’est que ce truc ??? mon disque dur fait sortie son ? J’ai pas vu de prise jack dessus pourtant !!! 
j’ai essayé
mais ça reste sans effet même après avoir relancé hdparm…
Quand à “DMA Setup Auto-Activate optimization” je n’ai pas trouvé la commende pour l’activer…
pour info est-ce normal :
[code]debian:/home/jean-louis# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 114 MB in 3.00 seconds = 37.99 MB/sec

Il s’agit d’un disque sata sur portable
merci d’avance !
