Card stopped being recognized in Linux Mint

What could be the cause of a Sandisk Extreme suddenly not being recognized?

I have both XP and Linux on the same machine, and use the card in both systems.

Today there was no respone in Linux, although the card worked well in XP.

Anybody having any clues?


in that case you can try to format the card with the windows computer and see if the card then works fine with the linux machine because maybe the format of the card was changed for some reasons. 

you can also try other cards with the mint machine to see if maybe the port is defective or something else happens there.
