ok my sd card has gone crazy. seems my sd has been erased, i et the Blank SD card notification, and then says SD card blank or has unsupported filesystem. i open rom manager and it says it needs to be mounted to use rom manager. i open astro and it says error creating external cache i was going to just erase everything off the card using my pc since i have all my files on there. but when i put it in a adapter and insert it in my pc it wont read it either. is my sd card just unsable now?
