Erreurs entrées/sorties sur disque

Sommaire

1 Short offline Completed without error 00% 0 -

Bonjour,

Je ne suis pas sûr d'être sur le bon forum mais je n'ai pas trouvé mieux, alors voici mon problème.

J'avais un NAS qui a rendu l'âme mais les disques semblaient toujours ok. J'ai monté l'un des deux dans un boîtier usb, sans problèmes (après reformatage bien sûr) !

J'ai installé l'autre dans ma tour mais j'ai voulu d'abord vérifier ce qu'il y avait dessus au cas quelques fichiers n'auraient pas été sauvegardés. J'ai donc tenter de le monter en jouant avec mdadm, assemble, /dev/md, etc., le tout, hélas, sans succès. J'ai finalement renoncé et voulu le reformater pour l'utiliser comme disque normal.

Impossible, gparted diagnostique des erreurs entrées/sortie, et smartctl -a /dev/sdb donne ceci la sortie ci-dessous.

J'ai essayé de récupérer le disque en utilisant un autre superblock, sans résultat.

Quelqu'un(e) aurait une idée pour me sortir d'affaire ?

Merci pour votre aide.
