I am running the newest stable version of CM (7.1.0), and my SD card all of a sudden stopped working. I'm getting an "Ongoing" notification that says "Blank SD Card, SD card blank or has unsupported filesystem". It won't let me format or mount the SD card, but I can still go to the manage applications part of the phone and see all of the file data on the SD card, it is just grayed out and I can't use anything that is on it.
Is there any hope to recover what is on the SD card? If not, is there a way that I can at least get it functional again?
