It is only showing format SD card but it don’t getting firmat
Hello,
in that case you can try to format with a different pc to see if you can format the card there and then use it again normally, if there it is also not possible then the card seems to be defective and needs to be replaced.
to replace the card you can contact sandisk directly

What is the size & Class of the card you are using?
What is the device you are trying to use it in?
If new, know that these cards come pre-formatted from the factory. There is no need to format them again.
