Problème de recuperation de partition

#1 Post by kenshinsanosuke » 21 Feb 2013, 11:32

Bonjour tout le monde,
J'ai un soucis pour recuperer une partition et j'ai besoin de votre aide (j'ai recherché sur ce forum et sur le net mais je n'ai pas trouvé de réponse pouvant m'aider)

Après avoir réinstallé XP sur une machine, mon disque dur externe n'était plus accessible.
J'ai donc utilisé TestDisk, fait l'analyse étendu et fait un "rebuild BS" (je pouvais voir mes fichiers).
Maintenant le disque qui était de 450GB+ est listé comme étant un disque de 320GB et je ne peus plus lister mes fichiers.
En faisant une recherche étendu voici ce que j'obtiens :

Code: Select all

The harddisk (320 GB / 298 Gib) seems too small! (( 464 GB / 432 Gib)
Check the harddisk size : HD jumpers settings, BIOS detection...

The following partition can't be recovered:
Partition	Start	End	Size in sectors
>FAT32 LBA	303485	23 31 442712 31 17 285137139
Dans la fenêtre suivante, je ne peux rien faire à pars créer une nouvelle partition.

Voici les logs que j'ai obtenu après avoir relancé une analyse. (si besoin, je peux poster les logs de l'analyse étendue)

Code: Select all

Disk /dev/sdc - 320 GB / 298 GiB - CHS 305245 64 32
Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (320 GB / 298 GiB) seems too small! (< 464 GB / 432 GiB)
The following partition can't be recovered:
     FAT32 LBA            303485  23 31 442712  31 17  285137139

Results

interface_write()
 
No partition found or selected for recovery
Si quelqun peux m'assister sur ce problème ce serais vraiment génial.

Si le disque faisant 450 ou 500 Go et maintenant est visible avec une capacité moindre, sortez le disque du boitier USB, connectez-le directement en SATA, vérifier au passage son étiquette où est indiqué sa capacité, refaites un essai avec TestDisk.
