Tu me sauverais la vie, je me vois mal dire que je ne peux pas travailler lundi à cause d'une mise à jour. ^^

J'avoue que j'aurais dû faire une sauvegarde. Une grosse négligence de ma part.

Tu peux tenter de redémarrer normalement, mais si ça ne fonctionne pas, pas la peine d'insister.
Procure-toi un DDE et fais un signe dès que tu l'as.
 
Super.
Tu le branches et tu démarres en mode Recovery, puis tu donnes comme plus haut les retours de :

On est bien d'accord que le DDE peut être réinitialisé.
Si oui tu tapes la commande :
diskutil eraseDisk jhfs+ Clone GPT disk15
Puis tu donnes les retours
 
Bloc de code: 
-bash-3.2# diskutil eraseDisk jhfs+ Clone GPT disk15
Started erase on disk15
Unmounting disk
Creating the partition map
Waiting for the disks to reappear
Formatting disk15s2 as Mac OS Extended (Journaled) with name Clone
Initialized /dev/rdisk15s2 as a 233 GB case-insensitive HFS Plus volume with a 24576k journal
Mounting disk
Finished erase on disk15
-bash-3.2#
 
Donc tu vas ouvrir une seconde fenêtre terminal (Menu Terminal/Shell/Nouvelle fenêtre)
tu tapes la commande qui va éviter une mise en veille. Il faut bien entendu laisser le Mac alimenté durant la copie :
caffeinate -idmsu
Puis tu passes à l'autre terminal et tu tapes la commande :
cp -av /Volumes/"Macintosh HD"/* /Volumes/Clone
et là ça va défiler le temps de copier tes 80 Go.
Quand ce sera fini tu fais signe.
 
ça ne doit pas fonctionner :

Ce qui est dommage c'est qu'il n'apparait plus.
Peux-tu le débrancher et le rebrancher?
Puis donner les retours de
diskutil list
Tu est sûre de son bon fonctionnement?
