Testdisk siker

Az illető egy darab pendrive-on tárolta a nagyon fontos fényképeit és azokat az mp3-akat, amelyeket az autóban hallgat. Egyszer bedugta a pendrive-ot az autójába, majd onnantól kezdve nem talált adatot rajta. Így került hozzám. Ubuntu alá feldugva:

Hát, ez nem néz ki túl jól. A /dev/sdb1-et nem lehetett mount-olni.

Ismeretlen partíció, ismeretlen tartalom. Ekkor jött a testdisk.
