I have made partition of my 16GB sd card so long and was using it in my Redmi 1s.To day I felt the entire sd card has to bring back to its original postion.As I installed in my mobile syltools,I opened it it and directly went to delet thinking that it will delete the partitions and restore the original position.In the process it asked to unmount the SD card.As I was not aware there is an option in the settings,I switched off the phone and manually unmounted and mounted and switched on the mobile.Now the Sd is not detected by computer and unable to mount as well as to open the application syltools.Can any body can help me to bring back the SD card to usable form.
