I was using my 8gb sd card with my Android phone and it worked perfectly fine. Yesterday after restarting my phone it says, "Blank SD Card", I tried reinserting and restarting it many timrs but it still says the same thing and sometimes, "Damaged SD Card".

I tried reformatting it with my Android phone but it does nothing, it doesn't format it. I inserted it to my PC (the adapter isn't locked/write-protected), and my PC can't even read it. I tried formatting with my PC into FAT/NTFS/exFAT but it says "Windows is unable to complete the format. I also tried SD Formatter 3.1 but it can't format it too.

I inserted it to my Nokia phone and it works, it can read it, it can also send my files inside via Bluetooth. HOWEVER, it still can't format it!

Please let me know how do I get it to work again. And if possible, can recover my files inside.
Many thanks!!!
