Donc un arrêt au bout de quelques segondes +
Current_Pending_Sector est passé de 0 à 2 (pas de changement de
Reallocated_Sector_Ct au cours du test, mais c'est passé de 13 à 72 depuis le début de la discussion), et gnome-disks me dit 74 secteurs endommagés... Eh bien voilà, il va falloir s'en débarrasser, de ce petit sda
Merci moko138 et geole !
