Seagate HDD down, à cause de surcharge de tension, ramené dans la labo de Seagate, impossible de récupérer les données, PCB est court circuit, qui endommage aussi la ROM. Donc même remplacement de PCB ne sera pas fonctionner.
 
Vous avez une idée ?

If Seagate can't fix it...what do you expect?

Seagate recovery service does not repair the disk, they ask me to consult a 3rd party recovery company.

Then, yes, no choice , you have to go through a recovery company, costly but the only way to get back your data ( backups are essential etc)

Now, you have to answer the question : is my data important enough to pay the expensive recovery ?

The choice is yours
