Quando tento montar um disco existente, recebo a mensagem
sudo mount -t ext4 /dev/sdc1 /data
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Quando olho para o dmesg , obtenho

Então eu corro o comando
sudo e2fsck -p /dev/sdc1

Alguma ideia?
