Oooops y a plus rien, nouvelles informations

#1 Post by PaxGourou »

Bonsoir,
Ma Fedora 35 a planté, comme ça, sans prévenir et sans m'avoir envoyé ses vœux de bonne année. Avouez que c'est n'est pas sympa. Le pire étant qu'au moment de la réinstallation, un disque de 2 Tio nommé sauvegarde a ..... été complétement effacé :shock: Indication primordiale il est affiché "partition inconnue".
Je n'y absolument pas touché, souhaitant ardemment qu'un éclairé du forum me donnera la manipulation géniale qui fera que tout cela n'était qu'un mauvais souvenir....
Comment que je fais :?: C'est du ext4.
Après avoir lancé Testdisk, la partition apparaît, et si je fais P, le message "Can't open filesystem. Filesystem seems damaged." s'affiche, puis Deleted ...

Voici le log, les images suivent :

Hint for advanced users: dmsetup may be used if you prefer to avoid rewriting the partition table for the moment:
echo "0 3907020800 linear /dev/sdb 2048" | dmsetup create test0
