I have sd cards that were read by my macbook pro and then a day later they are unreadable. Please help
I have used the sd card to record things and the device I sued to record did not have any issues. I then placed the sd card into a USB card reader and put it into my Macbook Pro. I was able to see the videos and photos for a day. The next day there were no more videos or photos. What happened? How do I get it back?
