attention aux disques dur des laptops
Bonjour,
J'écris par rapport àce que j'ai lu ici:
http://www.generation-debian.org/forums/viewtopic.php?f=5&t=350
et à fortiori ici:
http://www.beranger.org/index.php?page=diary&2007/10/24/18/07/21-it-s-confirmed-gutsy-is-killing-
Dans ce second lien, il y a notemmment ce passage:
"Outrageous cases have been reported:
134,600 load cycles in 2.5 months — at this rate the drive would be dead
in 11-12 months!
56,000 load/unload cycles (and 150 power cycles) in 2.5 months — at this
rate the drive would be dead in 2.5 years!
73,600 load/unload cycles in 5 months — at this rate the drive would be
dead in 3.5 years!
-B 160 leads to 3 cycles per minute (180 per hour), leading to a
lifespan of 600,000/180/24=139 days (of continuous battery powered use)!"
Voici les mesures que j'obtiens sur mon laptop avec smarctl:
à 22h45:
# smartctl -d ata -a /dev/sda | grep -i cycle
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 1434
193 Load_Cycle_Count 0x0032 062 062 000 Old_age Always - 380685
à 22h50:
# smartctl -d ata -a /dev/sda | grep -i cycle
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 1434
193 Load_Cycle_Count 0x0032 062 062 000 Old_age Always - 380688
à 22h55:
# smartctl -d ata -a /dev/sda | grep -i cycle
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 1434
193 Load_Cycle_Count 0x0032 062 062 000 Old_age Always - 380689
à 23h15
# smartctl -d ata -a /dev/sda | grep -i cycle
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 1434
193 Load_Cycle_Count 0x0032 062 062 000 Old_age Always - 380692
donc en gros ça avance d'un peu moins de 3 en 5 mn pour le "
Load_Cycle_Count".
Qu'en pensez-vous?
Merci :-)
