USB - odzysk danych

[adstp@o2.pl]

Witam,
Walkman, który pełnił również rolę pendriva, padł (chyba uwalona elektronika) ale próbuje odzyskać z niego pliki, a właściwie w jakikolwiek sposób dostać się do niego.

#fdisk /dev/sdb
fdisk: nie można otworzyć /dev/sdb: Brak medium

W jaki sposób można, o ile to możliwe jeszcze, jakoś go otworzyć.

Po podłączeniu takie oto komunikaty:
