Perte de partitions après redimensionnement
Bonjour,
j'ai voulu redimensionner deux partitions sur mon disque dur de 500 Go, mais mon ordi a planté en plein milieu, et ces partitions sont maintenant inaccessibles. Voilà ce que m'affiche PartitionManager.
J'ai fait quelques recherches, et après avoir essayé testdisk, je suis tombé sur ce topic, dont j'ai suivi les instructions. Je colle donc ci-dessous les réponses des différentes commandes, en espérant que quelqu'un pourra m'aider à résoudre mon problème. Le disque n'a pas de problème matériel d'après smartmontools.
Merci par avance,
LAbare
