10.13 High Sierra blocage barre de chargement au démarrage de mon mac

Ce dernier fichier est pas possible à copier ? Je n’arrive pas à le télécharger sur le cloud non plus... Il aurait un soucis ? Il reste deux dossiers et c’est bon, on part ensuite sur le reformatage
 
Bloc de code:
-bash-3.2# df -H /Volumes/CLE
Filesystem     Size   Used  Avail Capacity iused      ifree %iused  Mounted on
/dev/disk3s2    62G    56G   6.1G    91%    2245 4294965034    0%   /Volumes/CLE
-bash-3.2#

J'ai de moi-même copié les deux dossiers en suivant les démarches que tu avais déjà indiqué. Tout s'est bien passé, je t'ai passé cette commande pour te montrer. Je n'ai plus rien à copier, donc si il n'y a plus de manipulation à faire, (à part retirer la clé correctement peut-être ^^) go pour formater, merci beaucoup pour ton aide et tes connaissances qui me sont précieuses, encore une fois
 
Me revoici.

- si tu es prête pour un reformatage avant réinstallation > repasse une commande :​

  • ce qui veut dire que le volume en question > s'il est monté > l'est en lecture seule (verrouillé). Impossible à réinstaller.

=> ces corruptions (erreurs radicales) d'entrée d'après reformatage dans un système de fichiers --> sont toujours l'indice d'un problème matériel : disque défaillant ou nappe SATA défaillante.
 
Donc la suite c’est quoi ?
Edit : je voulais plutôt dire est-ce qu’il doit y avoir inspection ? Je ne saurais faire ça seule, quel serait le coût d’une nappe SATA ?
Si changement de disque dur nécessaire, n’importe lequel fera l’affaire ?
