Je pense que le résultat n'est pas top. Je voulais savoir comment faire pour réparer(si possible) et isoler les secteurs défectueux avec la commande Fsck? J'ai vu des tutos mais c'est surtout quelles options mettrent avec la commande. Merci d'avance pour l'aide. Est ce que cette commande serait bonne?

Est ce que la commande fsck (mentionnée sur mon 1er message) ne peut pas faire plus facilement la réparation(si possible) et isoler les secteurs défectueux?

[cyrille]

je ne pense pas que fsck va "réparer" les badblocks

Tu trouveras ici une explication afin de savoir comment procéder
https://cbiot.fr/dokuwiki/freebsd-smart ... _badblocks

Mais garder en mémoire que si le disque commence à donner des signes de faiblesse, il faut faire des backups qui il peut lâcher sans trop prévenir...

[jumbo67]

Bonjour cyrille,
Merci pour le retour et la réponse à ma question sur la commande fsck.
Pour la réparation éventuelle de badbloks c'est justement ça que je ne comprends pas sur ton tutoriel. C'est pour ça que je préfère demander ce qu'il faut que je fasse.

1èrement: e2fsprogs est déjà installé sur mon système
2èmement: je pense que je n'ai pas besoin de faire cette commande:

Code : Tout sélectionner

# badblocks -v /dev/sda6 > bad-blocks

Puisque j'ai déjà le résultat des erreurs sur mon disque avec la commande badblocks.
3èmement: c'est là que je ne sais pas ce qu'il faut faire.
D'après ton tutoriel si je prends par exemple la 1ère erreur sur mon disque(57074448), est qu'il faut que je fasse cette commande?

Code : Tout sélectionner

dd if=/dev/zero of=/dev/sdb bs=1024 seek=57074448 count=8

Et si oui est ce qu'il faut que je fasse ça sur les 130 autres erreurs trouvées par la commande badblocks sur mon disque?
Désolé de demander mais c'est pour ne pas faire une fausse manipulation.
Merci.
jumbo67
PS: j'ai oublié de demander si il faut faire la commande dd volume démonté?

Hello,
J'essaye de voir cela ce soir et de prendre le temps de te répondre, débordé en ce moment
En attendant, je te conseille de faire un backup , c'est plus prudent

[jumbo67]

Cyrille,
Oui pas de soucis c'est pas urgent. Ça peut attendre. Je ne vais pas faire ces manipulations de suite. Je n'ai moi même pas trop de temps cette semaine.
Je sauvegarde tout sur un disque externe. Si le disque plante c'est pas grave. Il n'y a que le système dessus.

Salut,
