[Linux][hdd failure] Problème de disque dure défaillant

[jmfs jaimail <jmfs.jaimail@gmail.com>]

Bonjour,

 

Je suis sous debian Testing, j'ai un gros soucis avec un disque dur externe Usb. Les informations que j'ai trouvé sur google ne me rende pas trés optimiste sur la survie du disque et des données. Mais j'aimerai malgré tout sauver un maximum de donnée. S'il existe un moyen je prend...

Le disque est en ext2 ou 3.

 

Lors du branchement du disque Syslog indique :

Le montage du disque  échoue,
mount -t ext2 /dev/sdd1 Music/
mount: wrong fs type, bad option, bad superblock on /dev/sdd1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


Palimpset ne reconnait pas le type du volume, indique que le disque présente quelques secteurs endommagés; le test id 197 Nombre de secteurs en attente valeur=3 avertissement.

Je n'ai pas osé lancer les test de smart de peur d'endommager le disque.

Ne pouvant plus monter le disque je cherche le moyen de sauver mes données.

 

Merci pour toute info.
