Pbm Disque Dur Externe

#1 Post by audrey » 07 Dec 2013, 23:15

Bonjour,
Je ne peux plus lire les données contenues sur mon DD externe. On me demande de le formater. Ci-dessous le contenu du fichier testdisk.log (je n'ai pas réussit à joindre le fichier). Que dois-je faire svp ? J'espère ne pas avoir perdu mes données !!!
Merci beaucoup,
Cordialement,
Audrey

Dans le menu Geometry de TestDisk, augmenter de 1 le nombre de cylinder.
Dans le menu Advanced, essayez Boot et List. Si vous pouvez voir vos fichiers, copier les.

Bonjour,

Tout d'abord Bonne Année 2014 et merci pour votre réponse.

J'ai augmenté le nombre de cylindre (enfin j'espère que c'était ça!), j'ai remplacé 121600 par 121601. C'est ça ?
Ensuite, je suis allée dans 'Advanced', puis 'Boot', j'ai ça :

TestDisk 6.14, Data Recovery Utility, July 2013
Christophe GRENIER <grenier@cgsecurity.org>
http://www.cgsecurity.org


Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121600 255 63, sector size=512

Because these numbers change the way that TestDisk looks for partitions
and calculates their sizes, it's important to have the correct disk geometry.
PC partitioning programs often make partitions end on cylinder boundaries.

A partition's CHS values are based on disk translations which make them
different than its physical geometry. The most common CHS head values
are: 255, 240 and sometimes 16.




Enter the number of cylinders: 121601

Ensuite, 'Advanced' et 'Boot':

Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121601 255 63
Partition Start End Size in sectors
1 P HPFS - NTFS 0 32 33 121600 247 55 1953517568

Boot sector
Status: Bad

Backup boot sector
Status: Bad

Sectors are identical.

A valid NTFS Boot sector must be present in order to access
any data; even if the partition is not bootable.





>[ Quit ] [Rebuild BS] [ Dump ]
Return to Advanced menu

Et enfin, 'Advanced', 'List':

Can't open filesystem. Filesystem seems damaged.

Qu'est ce que je peux faire de plus ?

Merci beaucoup de votre aide ?
