This question already has an answer here:
I have an apparently corrupted 128Gb SD Card. I do not care about the data (it was backed-up), but I would like to be able to reformat it and use it.
I tried under linux, without much success:
root@rennes:~# blkid | grep exfat
/dev/sde1: UUID="896E-A113" TYPE="exfat" PTTYPE="dos"
root@rennes:~# mount /dev/sde1 /mnt/usb
FUSE exfat 1.2.8
WARN: volume was not unmounted cleanly.
root@rennes:~# ls -lh /mnt/usb
total 128K
drwxrwxrwx 1 root root 128K Oct 19 06:53 Kiwix
root@rennes:~# umount /dev/sde1
root@rennes:~# mkfs.fat /dev/sde1
mkfs.fat 4.1 (2017-01-24)
root@rennes:~# mount /dev/sde1 /mnt/usb
FUSE exfat 1.2.8
WARN: volume was not unmounted cleanly.
root@rennes:~# ls -lh /mnt/usb
total 128K
drwxrwxrwx 1 root root 128K Oct 19 06:53 Kiwix
root@rennes:~# umount /dev/sde1
root@rennes:~# parted /dev/sde

root@rennes:~# umount /dev/sde1
etc… Even dd is hopeless.
I finally tried the formater tool from SD Card Association (http://www.sdcard.org/downloads/formatter), and got the following error message:
(Edit:
Invalid end of sector signature: 0x2DB6
exfat_check_validate_boot_sector returned error: 22 (invalid argument)
Initializing cached values failed: 22 (invalid argument)
Generated invalid volume. exfat_check_validate_boot_sector returned error: 22 (invalid argument)
)
So, my question is: can I format my SD card? How? Or should I just throw it away…
Thanks,
