Partition inaccessible mais existante

#1 Post by juicedaed » 24 Jan 2014, 15:48

Bonjour, au démarre d'un des PC de mes parents celui m'a lancé un CHKDSK.

Impossible de savoir si le PC avait été arrêté d'une mauvaise manière car ils ne l'utilisent que peu même si dans 99% des cas ils l'eteignent de manière conventionnelle.

Le CHKDSK a planté et depuis impossible de booter dessus. Je l'ai donc branché en en esclave sur un autre PC et tenté un nouveau CHKDSK car impossible d'accéder à la partition. Le CHKDSK me renvoit "La table maitresse des fichiers est endommagée. Abandon de CHKDSK".

Sous "gestion de l'ordinateur" de windows xp:

Le logiciel crystaldisk affiche cet état-là pour le disque (c'est le disque E):
Image

Recuva ne fonctionne pas.

Sur un autre logiciel (pc inspector), j'obtiens ceci (si ça peut aider):

J'en suis donc venu aux grands moyens en utilisant testdisk.

Menu Analyze:

Menu quicksearch:
Image

List des fichiers en appuyant sur "P":
Image

Menu "continue":
Image

Menu "deeper search":
Image

A savoir que j'ai tenté le "MBR Code" sur le premier secteur, je ne sais pas ce que ça a pu faire. J'avais trouvé cette astuce sur un forum mais je n'ai aucune idée du résultat que ça a eu.

Que dois-je faire?

Merci d'avance de votre réponse

EDIT: je rajoute le contenu de testdisk.log
ntfs_mft_load(): Failed.
Failed to load $MFT: Input/output error.
Failed to startup volume: Input/output error.
$MFT has invalid magic.

Dans le menu Advanced de TestDisk, essayez Boot, RebuildBS, List.
Si cela marche, choisissez Write et confirmer.
Si le secteur de boot est déjà identique à son backup, vous pouvez aussi essayer RepairMFT.

Bonjour, et merci de votre réponse.

Je réponds tardivement car étant étudiant je n'avais malheureusement pas eu le temps de m'en occuper avant.

Je viens d'effectuer les différentes manipulations proposées et malheureusement c'est un échec.

Après avoir effectué,
  • Advanced , puis Boot et RebuildBS j'obtiens ceci:

  • Avec l'option list, j'obtiens ceci:

  • Avec l'option repairmft, j'obtiens ceci:

Voici le log :
