j'ai eu un remord ce matin, j'ai essayé de supprimer les partitions de ce
disque qui m'a laché, puis en recréer une, et ça a marché...
j'ai quels outils pour vérifier avec certitude que ce dd marche encore ou
qu'il a vraiment des pbs ? Parce que j'arrive pas à comprendre que le
filesystem ait pu disparaitre tout seul alors que je ne travaillais mm pas
dessus, c'est qd la musique et le fond d'écron ont disparu que ça m'a fait
drôle...
voici les tests que j'ai fait pour l'instant (en gros tous ceux que vous
m'aviez dit de faire déjà), si qqun peut me donner son avis sur l'état du
disque à partir de ça. J'ai aussi un badblock en cours mais ça ce sera plus
long je le posterai ttaleur.
Si vous avez d'autres conseils de tests je suis preneur.
Merci
