Try Photorec to see if it finds anything.
If that fails the SD card maybe broken.
You could try to duplicate the drive with ddrescue and check the ddrescue log file as well.
Afterwards you could try out write operations by trying to delete the whole card using the clean function of diskpart or overwriting using /dev/zero as source device in linux.
