Partition illisible

#1 Post by stephane01 » 28 Aug 2013, 08:36

Bonjour

j'ai un disque du externe de 3 To en 4 partition
- 1 partition EFI
- 3 partition de 3TO1, 3TO2, 3T03 et de 930 Go chacunes

Du jour au lendemain, tout à disparu (le disque était branché sur ma freebox, donc a priori pas d action spécifique).

J'ai donc lancé testdisk et je voudrais svp savoir comment récupérer mes données

Ci dessous le log du search

D avance merci de votre aide

Re: Partition illisible

#2 Post by cgrenier » 05 Sep 2013, 14:29

Le problème vient de la capacité retournée par le disque 800Go au lieu de 3 To.
La table des partitions est correcte, pas la peine d'utiliser TestDisk.

Vérifier la capacité disque avec l'utiliataire hdat2. Peut-être un problème de DCO ou HPA.
