Disque dur externe passé en RAW

#1 Post by aurel » 26 Jan 2017, 18:28

Bonjour,
Mon disque dur externe SAMSUNG est passé en RAW et je souhaiterais récupérer mes données et réparer mon disque pour le réutiliser si possible.
J'ai donc lancé Testdisk:
- J'ai lancé un create et selectionné mon disque dur externe
- TestDisk me detecte automatiquement l'option non partitioned media
- Après une analyse en Quick search et Deepsearch il me met le message suivant: "No partition found or selected"
A ce moment là je ne sais pas quoi faire, je vous joint le fichier log...
Si quelqu'un peut m'aider pour la suite ?

Le fichier log:

Rechercher des partitions à l'intérieur d'une partition est inutile.
Lisez https://www.cgsecurity.org/testdisk.pdf chapitre "Repairing filesystem"
Dans le cas précis, "Repairing filesystems from Windows" et au besoin "TestDisk: Repairing FAT boot sector"

Je suis en train de faire le "TestDisk: Repairing FAT boot sector"
Il me demande de choisir un type de partition.
Quelle type dois-je choisir ?

Merci d'avance.
