Eu tenho um SDCard que possui uma partição ext4 que foi muito danificada. Se eu tentar montar, ele exibirá:
mount: mount /dev/mmcblk0p8 on /media failed: Stale file handle

Posso tentar algo mais para recuperar a partição, sei que posso rodar o photorec, mas me pergunto se ainda consigo consertar a partição...
ATUALIZAR
A saída do dmesg tem muitas mensagens como esta:
[dom may 14 17:18:28 2017] mmcblk0: error -110 sending stop command, original cmd response 0x900, card status 0x900
