C'est bien ce que j'ai vu malheureusement...
Et le retour de la commande demandée semble aller dans ce sens :

Après c'est bizarre c'est disck1 alors que javais l'impression qu'en faisant la manip sur l'utilitaire de disque et le SOS après redémarrage j'ai fait des manip sur un disk2... J'ai du rêver...
Comment être sûr qu'un formatage peut régler le problème ? Est-ce un problème de SSD ? Est-ce que ça peut être un problème de carte mère ???
Merci
