I have a 16g micro SD card and it was fine until one week ago, I used an android app for downloading torrent called uTORRENT. I started to download a movie on my mobile left it for about half hour and when I came back and checked the downloading progress I noticed that the downloading stopped and a message was shown on the downloading line that say: write to disk error.
After this my SD card became write protected and I couldn't delete or download any thing to it.
I tried several ways and programs to remove the write protection from my SD card but I couldn't.
I also cheked my SD adaptor and it was unlocked. I couldn't delete or format the memory even on my computer.
Please help me with my problem.
