Problème de système de fichiers

#1 Post by xv6666 » 05 Apr 2016, 19:55

Bonjour, Windows me propose de formater mon DD externe (stockage de données), je ne peux pas acceder aux données. Voici ci dessous le rapport testDisk. Que puis je faire?

merci d'avance pour vos retours, XV

Lorsque TestDisk vous propose de sélectionner le disque, choisissez le disque physique contenant la partition F: (pas F: directement), confirmez le type de partition, Boot, RebuildBS, List. Si vous voyez vos fichiers, choisissez Write, confirmer, Quit et redémarrer. Postez le nouveau log en cas de problème.

Bonjour RebuildBS puis write,
J'accède bien au contenu du disque avec list. Pourtant après redémarrage c'est toujours le même symptôme.

merci pour votre retour, xv

Il y a des secteurs défectueux. Utilisez TestDisk, Advanced, List pour copier vos fichiers.

Une aurtre solution est de cloner le disque vers un disque vierge de capacité identique ou supérieure en utilisant gnu ddrescue depuis un Live CD/DVD/USB Linux. Voici un tutorial un peu ancien https://www.cgsecurity.org/wiki/Damaged_Hard_Disk

Bonjour et merci pour votre réponse. Les fichiers ont été copiés et le disque reformaté. Peut il etre réutilisé sans restrictions après le reformatage?

cordialement, XV
