Clé USB irrécupérable ?

Bonjour,

je crois que j'ai grillé une clé USB en la branchant sur un ordinateur qui surchauffait (mais ça, je m'en suis rendu compte *après* ) !

Je tairai le nom de l'OS pour ne pas nommer un grand éditeur de logiciels de Redmond, Washigton, USA. ;-)

Je viens de la retrouver, en la branchant directement, sans cable, sur mon Ubuntu, j'ai les messages suivants à répétition dans /var/log/syslog et /var/log/kern.log:

Est-ce qu'il y a un moyen de récupérer la clé en faisant une sorte de formatage bas niveau ou une autre action ?
