I have a MicroSD card and it has been working real good until now. I accidentally unplugged my Pi 3 model b and now the SD card isn't formatting with the SD formatter, or erasing, and on my Mac,disk utility is no help either. In fact, none of my devices are recognizing it anymore. And it no longer works with the Pi. This is important because I need this SD card formatted. How do I fix it?
Thanks for all your help.
