I have samsung galaxy s4 and 64GB Kingston Micro SD Card. One time I took out the SD card out of my phone (safely) and placed it on an old phone (ZTE blade [Orange San Francisco]) to see if it will work on there and it didn't recognise as I later found out that it didn't support 64GB. So when I put the micro SD card back on the galaxy s4, it's not recognising it anymore and saying that it is "Damaged SD card" and that the only option is to format it. I tried putting it on to the computer but it only asks me to format it. I would have formatted but I have many important data on it.
Please help me for any solution, Thank you very much.
