[RESOLU] Récupération de données d'un disque endommagé

apollinaire · Le 08/12/2009, à 01:02

[Solution du problème]
Installer dd_rhelp

sudo sfdisk -l

pour repérer l'adresse du disque défectueux
Se procurer un nouveau disque de taille supérieure au précédent, le formater en NFTS ou ext3 (mais pas en fat)
Avec dd_rhelp, faire une image du disque défectueux sur le nouveau disque.
D'abord monter le nouveau disque (sur sdd1 dans mon cas)

sudo mount /dev/sdd1 /mnt

puis lancer dd_rhelp (le disque défectueux se trouve sur sdc1 dans mon cas)

sudo dd_rhelp /dev/sdc1 /mnt/monimage.img

L'opération a mis plusieurs jours sur mon disque de 500 Go...
Ensuite créer un répertoire et monter l'image sur ce répertoire

mkdir recup
sudo mount -o loop /mnt/monimage.img recup/

Aller ensuite dans recup pour avoir accès à vos fichiers, dans mon cas la procédure a fonctionné (non sans mal et quelques erreurs...)
Pour plus de détails, consulter la suite du fil.
Bon courage.

Bonjour,

Dès que je branche mon disque dur externe /dev/sdb1 , toutes les ressources du processeur sont utilisées.
Au bout d'un certain temps, seuls les dossiers et fichiers s'affichent, je n'ai pas davantage d'accès.
De plus quand je tente de le démonter (umount), "Cannot unmount because file system on device is busy"

démontage : /media/STOREX: périphérique occupé.
       (Dans certains cas, des infos sur les processus l'utilisant
        sont récupérables par lsof(8) ou fuser(1))

la réponse à la commande lsof, je n'y comprends rien (beaucoup trop long), je peux simplement vous donner ce qui semble être relatif à l'USB ?

usb-stora 4142       root  cwd   unknown                                /proc/4142/cwd (readlink: Permission denied)
usb-stora 4142       root  rtd   unknown                                /proc/4142/root (readlink: Permission denied)
usb-stora 4142       root  txt   unknown                                /proc/4142/exe (readlink: Permission denied)
usb-stora 4142       root NOFD                                          /proc/4142/fd (opendir: Permission denied)

Pour info, je crois que le disque de 500 Go était trop rempli.

Voilà,

Merci d'avance à ceux qui pourront me donner accès à mes données.

je repasse. Sujet noté.

Quel est le système de fichier sur ce disque ?

Peux-tu donner le retour de dmesg quand tu branches le disque ?

As-tu essayé en console single user (soit en utilisant le mode recovery, soit en passant en telinit 1) pour que ton disque ne se monte pas, de voir ce qui se passe si tu le branches (les ressources sont elles aussi utilisées ?) => est-ce un souci matériel (problème dû au branchement) ou logiciel (problème du au montage) ??

Voici quelques pistes de recherches. Je n'ai jamais eu le souci, peut-être ton disque a-t-il des problèmes plus graves, beaucoup de secteurs défectueux on difficilement accessibles, d'où le temps très long pour accéder aux données...

Bonjour, merci pour ton aide.

Il s'agit de FAT32,
voici le retour de demsg

As-tu essayé en console single user (soit en utilisant le mode recovery, soit en passant en telinit 1)

Je ne suis pas suffisamment expérimenté pour toutes ces manips mais je vais essayer.

Les fichiers et dossiers mettent en effet beaucoup de temps à s'afficher.

[Edit] Je viens d'essayer le recovery mode, le recovery menu ne fonctionne pas...

visiblement ton disque a bien des soucis matériels au vu du nombre de secteurs illisibles.

pour éviter que celui-ci ne se monte automatiquement, passe en tarminal avec Ctrl+Alt+F1 puis tape la commande :

sudo telinit 1

Ensuite branche ton disque et rapporte nous le résultat de

lsusb

et

sudo sfdisk -l

Jette en attendant un oeil à ma signature pour te préparer et installer dd_rhelp et testdisk (va chercher directement la version static sur le site cgsecurity, c'est la 6.12-WIP je crois).

Pour bien faire, il te faudrait aussi un espace disque d'au moins la taille de la partition que tu veux récupérer sur ce disque, ou au mieux de la taille de tout le disque (voir plus serait mieux).

Tu risques d'avoir du mal à récupérer tes données...

rmy · Le 10/12/2009, à 14:10

Il me manque pour sfdisk la taille de blocs (1024 ?) Ton disque est bien un 500Go ?

Sinon ton disque semble reconnu, le problème matériel touche donc plutôt ta FAT.

L'idée est donc de réaliser une image disque de celui endommagé vers un autre support sain avec dd_rhelp, puis de travailler sur cette image...

Dis moi quand tu es opérationnel, je reste à l'écoute.

apollinaire · Le 14/12/2009, à 08:44

Il s'agit bien d'un disque de 500 Go.
Je viens de recevoir un nouveau disque de 640 Go, je suis donc prêt à procéder aux opérations et tenter de sauver ce qui peut l'être.

rmy · Le 14/12/2009, à 09:50

as-tu installé dd_rhelp ?

La 1ere étape consiste à faire une image de ton disque à l'identique

apollinaire · Le 14/12/2009, à 15:42

Avec dd_rhelp le disque restait illisible, je suis donc passé par testdisk pour réaliser une image du disque mais c'est vraiment très lent.
De plus sur le nouveau disque de 640Go, seuls 560 Go sont annoncés disponibles. Les problèmes ne seraient pas liés ? problème de lecture du fat ?
[Edit] Finalement testdisk ne me fait qu'une image de 4Go !
Je viens donc de lancer dd_rescue qui semble fonctionner pour l'instant... wait and see...
[Edit2] L'erreur c'était bien évidemment d'avoir formaté le nouveau disque en fat32 => pas de système de fichiers de plus de 4Go => préférer ext3 ou NFTS

Très lent comment ?

??

sudo sfdisk -l

avec les deux disques branchés ?

N'oublies pas que je ne vois pas ce que tu fais et ce qui se passe. Efforces toi d'être le plus précis possible dans les retours que tu postes, voir copier/coller les messages des softs si possible, afin que je me rende compte de ce qui se passe.

pour dd_rhelp, tu as oublié les "/", et heureusement : tu procèdes à l'envers, tu es en train de tenter de copier ton disque vierge sur ton ancien disque

Il faut que tu montes ton nouveau disque, par exemple dans /mnt

sudo mount /dev/sdd1 /mnt

ensuite tu fais l'image avec dd_rhelp :

sudo dd_rhelp /dev/sdc1 /mnt/monimage.img

Je dois attribuer des droits en écriture ?

Bad block: 72457

Input/output error, c'est normal ?

rmy · Le 14/12/2009, à 21:14

C'est les secteurs défectueux, dd_rhelp devrait les "esquiver" après quelques tentatives pour y revenir plus tard. L'intérêt d'une telle image, c'est que justement tu ne perds pas le temps d'accès aux secteurs def.

Suivant l'état d eton disque, la copie peut durer.... très longtemps.

500Go, ça peut déjà prendre 8 à 10H... Mais avec des secteurs defectueux, ça peut vite monter à 24/48H

En fait c'est toi qui va décider quand tu jugeras que tu en as récupéré assez... mais je te conseille d'être patient. (J'ai déjà fait tourner un disque pendant 17 jours...)

apollinaire · Le 14/12/2009, à 21:31

Maintenant monimage.imf fait 4Go et dd_rhelp n'arrête pas de me balancer en cascade des

tu peux le stopper et recommencer tout à zéro. J'avais pas fait gaffe que ton disque de 640Go était en FAT32... 4Go c'est la limite de taille d'un fichier sur de la FAT32.

Commence donc par formater le disque de 640Go en NTFS (voir en ext3 pour le temps de la récup), et reprends la démarche.

Désolé pour le contretemps.

apollinaire · Le 14/12/2009, à 21:40

Okay, merci, en ext3 donc.
Pour le temps, je ne suis plus à ça près!
One more time again, wok'and woll

rmy · Le 14/12/2009, à 21:46

Tu as bien raison de le prendre comme ça

La récup est un chemin long et souvent douloureux, pavé d'embuches... Ou patience est mariée avec sérénité.

rmy · Le 14/12/2009, à 21:48

Un détail important tout de même :

Si ça devient vraiment long et que par exemple, l'ordi est dans la pièce ou tu dors... Tu peux stopper dd_rhelp avec Ctrl+C et reprendre plus tard grace au fichier de log.

apollinaire · Le 14/12/2009, à 22:15

Et je relance avec la même commande ? inutile de spécifier de se référer au log ?

rmy · Le 14/12/2009, à 23:22

si les disques sont montés dans le même ordre avec les mêmes lettres, lorsque tu tapes la même commande il ira chercher le log au même endroit.
