Disque dur externe se deconnecte tout seul

[fadarct]

Bonjour,
j'ai un disque dur externe Lacie de 1 To.
Depuis aujourd’hui quand je le connecte il m'affiche ce message au bout de 5 mn sans que je ne fasse quoi que ce soit puis il se deconnecte :

J'ai été voir dans la console et j'ai trouvé ça :

Est-ce quelqu’un a une idée de quoi ça peut venir ?

Merci

Bonjour,

Il faudrait vérifier le bon fonctionnement de l'alimentation du disque dur.

J'ai eu il y a quelques temps des problèmes avec un disque dur LaCie qui peinait à monter sur le bureau au démarrage du Mac. Il s'est avéré que le problème venait de l'alimentation du disque dur. Je l'ai changé (vive les alimentations externes !) et depuis plus de problème.

Sinon, il faut essayer sur un autre port du Mac (si c'est possible), un autre mode de connexion (USB, Firewire,...) du disque dur au Mac (si c'est possible), avec un autre câble.

Et aussi tester dans une autre session.

Merci pour ta réponse
Je n'ai plus eu ce problème depuis mardi. Mais je vais quand même surveiller ça au cas où ça me le refasse.
