difficult to say ...
un peu décu , je l'ai prise pour donner de gros fichier (+de30go) a mon frere , et surtout une grande marque pour ne pas avoir de soucie , in n'empeche que dés le 1er transfert , bug , sur bug sur bug ...
I've contacted the after-sales service, and the response has not been very helpful ...
So I did a Low Level Formatting of the key myself, and since it works very well !
So the key book is badly formatted, the service is a mess, in the end, fortunately I know a bit about it otherwise it's a mess xD
