On le voit pas là.
Tu peux tenter de le brancher sur l'autre port?

 

[Deleted member 1099514]

Voici le disque dur externe

Retire la clé et enfonce le comme il faut. Pour le branchement coté DDE il ne faut pas hésiter à forcer un peu.

J'ai bien enfoncé le DDE voici le resultat de la commande

 

[Deleted member 1099514]

Pas mieux. Il est neuf ce disque?
Tu peux redémarrer le Mac (toujours en mode Recovery) en laissant le DDE connecté, puis refaire un
diskutil list

 

[Paul94500]

Oui c'est un disque dur neuf jamais utilisé , je l'avais dans mes affaires
comment on redemare en mode Recovery?

 

[Deleted member 1099514]

Tu tapes
reboot
Puis quand le mac redémarre, tu appuis sur cmd+r. C'est ce que tu as fait au début. Non?

 

[Paul94500]

Oui c'est bon j'ai redémarrer ,
Je n'ai jamais utiliser ce DDE externe je viens d ouvrir son emballage je ne l'avais jamais utiliser
L'ordi ce rallume

J'ai retirer la clé usb et j'ai brancher le DDE a la place ou etais la clé USB voici le resultat

 

[Deleted member 1099514]

Ha c'est mieux.
Donc tu vas faire :
diskutil erasedisk jhfs+ Save_Macintosh_HD gpt disk21

 

[Paul94500]

-bash-3.2# diskutil erasedisk jhfs+ Save_Macintosh_HD gpt disk21

[Deleted member 1099514]

C'est pas normal.
Retente avec :
diskutil erasedisk jhfs+ Save_Macintosh_HD /dev/disk21

[Deleted member 1099514]

Peux-tu quitter le terminal, puis passer par l'Utilitaire de disque, sélectionner le DDE puis "Effacer" et la bien vérifier que Schéma GUID et format Mac os x journalisé sont bien sélectionnés et le nommer Save_Macintosh_HD

 

[Paul94500]

C'est écris qu'en effaçant tout les données seront perdu , j'ai changer le nom , j'ai enlever le Sans titre qui etais marquer et la j'ai marquer Save_Macintosh_HD
Alors je clique sur effacer ?

 

[Deleted member 1099514]

Stop..

C'est pas sur le disque interne, mais sur le DDE qu'il faut faire cela.
Tu ne touches pas à "Sans titre". C'est là où sont tes données.

 

[Paul94500]

Ah' d'accord , voici les deux disque qui affiche je ne vois pas le
DDE
Je vois que le DD interne
Et en bas Image disque

 

[Deleted member 1099514]

Donc soit ton mac a un petit souci et ne reconnait pas ou mal les périph usb, soit il manque un peu de jus, soit ton DDE est HS.

Tu peux déjà essayer avec un câble en Y (adapté à ton disque) : https://www.latelierducable.com/help/le-cable-usb-double-ou-en-y-pourquoi-faire
Sinon acheter une clé usb de quantité suffisante pour sauver tes données.

 

[Paul94500]

Je pense que le soucis dois venir du port USB par moment il marche et apres il ne fonctionne plus mais bon ce n'ai pas bien grave , on peut continuer si j'ai perdu mes donner ce n'ai pas grave j'ai certaines photos dans mon tel et ma tablette et sur iCloud , j'ai pas de choix alors je vais perdre les donnée une fois l ordi rétablir je verrais Pour le port usb
