SanDisk Ultra Series Class 10 - 16GB..

I have installed Recalbox a few times now.. Everytime it runs smoothly for one day or so and suddenly i cant do anymodifications to the system. I cant update , cant remove files or roms etc. The SD-card is going into read only mode and i don't know why or how to get it back into read\write mode. Is there any way i can get it back to read write mode without installing the whole system once again and get it to stay there? Perhaps add something in the config to prevent this from happening again?
