I HAVE A WINDOWS NOT COPY ALLOWED

I have gone through the same problem while copying data to my SD Card. But there i find a sliding lock which prevents data to be copied into card when it is slided to lock. So, if you want to copy some data to similar device, or going through the similar problem, you can recover using the same mechanism.
