So I have a Boss BR-600 and my band and i just finished recording a song. However, when i tried to put it on my computer a message popped up that said the card was corrupt and cannot be used. And when i put it back in the BR-600 it also said it was corrupt.

Does anyone know any good programs that could recover the data on it?
or know anyway to fix it?

the data is locked up in a castle protected by a fierce dragon. You must be swift and cunning. Only when you reach the data, can you have its hands in marriag- I mean get the lost data back.
