concernant les manips du laptop mode décrites , j'ai tout essayé, sans succès
la seule commande qui semble efficace est hdparm -B254 /dev/sda
le "start/stop count" s'est quasiment stoppé
le "G-Sense_Error_Rate" a augmenté de 170 en 20h effectives de fonctionnement, avant c'était un craquement toutes les 5/10 secondes
le "Reallocated_Event_Count" augmente toujours
mais c'est en silence, il n'y a quasiment plus de craquements.
j'ai également effectué plusieurs paramétrages expliqués dans les forums ubuntu afin de limiter les réveils du disque :
http://forum.ubuntu-fr.org/viewtopic.php?id=158753&p=39
configuration du noatime dans le fstab
UUID=6a7bbd53-ee68-42a4-8c60-96c4e7407f09 / ext3 noatime,defaults,errors=remount-ro 0
redirection des tmp vers la ram dans le fstab
tmpfs /tmp tmpfs defaults,noatime,mode=0777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=0777 0 0
Je suis toujours à la recherche d'infos complémentaires
il y a cette option spécifique à samsung pour smartctl que je n'arrive pas à passer en commande.
