Erreur de disque dur DRDY: est-ce un crash

5

J'utilise IBM Thinkpad, 1,7 GHz, 512 RAM avec Linux Mint 9 installé. J'ai deux partitions en plus de root.

Une des partitions est devenue en lecture seule hier, après quoi j'ai redémarré mon système. Il est extrêmement lent avec DRDY Erreur: mon disque dur est-il écrasé? Journal des erreurs lors du démarrage.

Differences between boot sector and its backup.

En plus de la ligne "ata 1.00: status", il devrait y avoir une lecture "ata 1.00: error ..." qui vous indiquera l'erreur exacte.

Le journal des erreurs SMART contient des informations utiles:

Erreur: secteurs UNC 5 à LBA = 0x00001b1a = 6938

Cela signifie une erreur non corrigible. La dernière commande était un DMA READ, il s’agit donc d’une erreur de lecture. Il semble que les secteurs 6938 à 6943 ne sont pas lisibles.

En outre, dans les attributs SMART, nous pouvons voir qu'il y a 40 secteurs réalloués avec succès, 82 secteurs en attente de réallocation et 1 erreur non corrigible (probablement celle du journal):

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE

Tout indique que le lecteur est en panne, alors sauvegardez les données immédiatement. Si vous ne pouvez pas copier les données à cause des erreurs, utilisez ddrescue pour créer une image de la partition en ignorant les blocs défectueux. ce tutoriel est très utile.

DRDY n'est que le drapeau de disponibilité de l'appareil. ERR, et surtout UNC (uncorrectable) sont le problème.
