USB Stick recovery in linux

[geerttttt]

Ik heb een usb stick wat een bootable usb stick met OpenElec erop. Hier staat ook wat custom made software op van mij.

Nu heeft deze stick ineens de geest gegeven pas geleden. Dat wil zeggen, ik zie nog het openelec GRUB boot logo... maar daarna blijft hij hangen en geeft hij even later een fout dat hij het label "Storage" niet kan mounten.

Koppel ik hem aan mijn linux pc, dan zie ik dit in dmesg:

code:

Ga ik nu proberen om sdf2 te mounten via mount /dev/sdf2 /home/test , dan krijg ik een fout dat het bestandssysteem onbekend is, en komen de volgende regels erbij in dmesg:

Wat kan ik nog doen? Ik wil de data redden omdat ik (stomme ik) geen backup heb van mijn eigengemaakte software!

Help!
