Partitions qui se chevauchent + read error

#1 Post by sportbillyboy » 26 Jan 2014, 14:47

Bonjour,

Je n'arrive plus à lire ou écrire sur mon disque dur USB.

Testdisk m'affiche 2 erreurs :

1) 2 partitions (Sys=74 et DiskSecure MB) se chevauchent

Partition table type (auto): None
Drive H: - 500 GB / 465 GiB
Partition table type: Intel

Analyse Drive H: - 500 GB / 465 GiB - CHS 60801 255 63
Geometry from i386 MBR: head=115 sector=50
BAD_RS LBA=1920221984 5880424

check_part_i386 3 type 72: no test
Current partition structure:

2 * DiskSecure MB 119533 19 23 224380 65 21 1684369952

Bad relative sector.
3 * Sys=72 10496 93 40 10496 93 39 0

Bad relative sector.
Only one partition must be bootable
Space conflict between the following two partitions
1 * Sys=74 119528 74 3 232582 38 44 1816210284
2 * DiskSecure MB 119533 19 23 224380 65 21 1684369952

Laquelle des 2 supprimer ?
Que faire de la 3ème ?


2) read error

Read error at 391/126/56 (lba=6289408)

est-ce un problème hard ou soft ?

H: est déjà une partition. Il faut soit
- sélectionner un "PhysicalDisk" puis PC/Intel
- sélectionner H: puis None
et aller ensuite dans le menu Advanced.

Mon problème n'est toujours pas résolu, mais je suis tombé sur cet extrait de http://www.cgsecurity.org/wiki/Advanced ... MFT_Repair :
"If both MFT and MFTMirr are damaged and thus cannot be repaired using TestDisk, you might want to try commercial software like Zero Assumption Recovery, GetDataBack for NTFS or Restorer 2000."

Donc à priori rien d'autre à tenter avec Testdisk. Dommage. Quelqu'un a-t-il une (bonne) expérience avec un de ces outils ? A quel coût ?

Ils ne sont pas donnés... Vous pouvez toujours utiliser PhotoRec mais les noms de fichier d'origine ne sont pas retrouvés.
