Disque 4To partition sector doesn't have the endmark 0xaa55

#1 Post by Mikael007 » 16 Oct 2014, 20:10

Bonsoir,

Je suis victime d'un disque WD 4To récalcitrant transformé en RAW. Après recherche j'ai découvert testdisk et ce forum.
Je viens donc solliciter de l'aide en toute humilité.

En lançant testdisk celui ci m'indique une erreur "partition sector doesn't have the endmark 0xaa55"
J'ai lancé toute la nuit dernière un scan sur le lecteur g: sans résultats.
Après avoir chercher un peu sur le forum j'ai lancé à l'instant un scan d'un physicaldrive8 - 4000 GB en intel et il en est à 4 %.

Est ce que je suis sur le bon chemin ?

Merci de votre aide

Bonjour.

tout d'abord merci d'avoir pris du temps pour me venir en aide.

j'ai relancé un scan sur le lecteur g: et voici le rapport

en faisant vos directives je n'obtiens aucune partition et n'ai pas non plus accès à mes données :/

dois je faire le deuil de mes informations ?
