Hello,
I have an SD card which was been used in my dash cam.
Recently the dashcam stopped recognising the sd card.
I put it in the PC and formatted the card.
Now it says 0gb free of 32gb.. But there's nothing on the card.
So the PC recognises there's a 32gb card inserted.
Any ideas?

edit:
assuming that you just want to restore the card to a usable condition and don't care about the footage on it, you should just reformat the card.
Download the formatter tool from SDcard.org and reformat it as FAT filesystem

If you've been using the card in your dashcam and it was not a 'high endurance SD card', its possible it might have exhausted it's read/write cycles and can no longer be used.
