Partitions can't be recovered:

#1 Post by panchino » 09 Jan 2016, 21:36

Bonsoir,

Après de nombreux essais de "récupération d'un disque" avec votre logiciel, et des recherches sur le forum, je n'arrive pas bien à comprendre ce que je dois faire, comment interpréter les logs, ce que je puis espérer pour remettre la main sur les données de ce disque.

Version de testdisck testées :
7.0 win64
7.1 WIM (64)
7.1 WIM (32)

Voici l'un des logs produits, en espérant que vous puissiez m'éclairer sur la marche à suivre :

Il s'agit d'un disque USB qui "un jour" a cessé d'être accessible.
Il est toujours bien apparu dans la liste du poste de travail de windows.
Avant l'utilisation de Testdisck 7.0, tenter d'y accéder ne donnait simplement rien, après avoir tourné quelques minutes.
Maintenant, windows me propose désormais de le formater.
=> Je l'ai aujourd'hui branché sur un autre port USB, et il me harcèle de propositions de formatage (1 toutes les 2 secondes, et qui s'empilent).

Ce disque Samsung possédait un logiciel interne de cryptage que j'ai un jour utilisé.
Avant que je le formate, sous win XP.

C'est un disque de données.

Ces informations sont-elles suffisantes ?

Si mes souvenirs sont bons (le plantage date de 2013), le disque externe a cessé d'être accessible à la suite d'un redémarrage forcé de windows.
Mais l'application qui a causé ce plantage ne faisait pas partie de celles contenues dans ce disque.
Il était juste branché à ce moment là.


Sinon, j'ai essayé Testdisck 7.0 (win 32) sur une OS windows 8.
Toujours exécuté en mode administrateur.
En voici le log :

Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (640 GB / 596 GiB) seems too small! (< 1524 GB / 1419 GiB)

You will have to reboot for the change to take effect.

TestDisk exited normally.
Mais le résultat est le même : Pas d'accès au disque après le redémarrage PC.

Re: Partitions can't be recovered:

Dénouement
Le disque externe ne pouvait pas être formaté par windows (7, SP1), inaccessible.
J'ai utilisé un logiciel de gestion de disque (EaseUS) pour recréer une partition, avec la procédure qui suit :
- Branchement du disque externe => trouver le bon port USB
- Lancement du logiciel de gestion => qui charge indéfiniment pour s'ouvrir (reconnaissance du disque difficile)
- Débranchement du disque dur => là, le logiciel arrête de mouliner et affiche les DD du système, et notamment le DD qu'on vient de débrancher
- Rebranchement du DD
- Création d'une partition unique => un peu long mais finit par aboutir

A partir de là, windows reconnaît le disque dur.
J'ai pu utiliser un logiciel de récupération de données (récuva en l'occurrence).


En vous remerciant, et bonne continuation !
