so if it really is empty, no files there, fully accessable but nothing on it, there's nothing you can do, is it?
I had an sd card that nothing could read which was working before. I managed to retrieve all the files from it.
If that's how it is for you too I might know a program that could help but if the sd card is empty you can't do anything I think...
It's empty. I'm slowly redownloading all of my old files.
