Nevertheless, people frequently lost their important data stored on SD cards in many scenarios. It is frustrating especially when you have no backup, just like the real question from Microsoft Community below.
I recently transferred some important files to an SD card. But later when I checked it, a window showed up and said that it needs to be formatted (whhhaaaat!) for some volume error thing...something like that. I want to know if I can still get my files back, or if I do something wrong to this SD card. Can someone give me a list of what might have happened or any advice on SD card data recovery? Thank you!
