Un grand merci pour ton aide et tes conseils.

Je vais m'empresser de faire une sauvegarde et de changer ensuite soit le disque dur, soit le PC.

Bonne journée, encore merci.

Bonjour,

merci d'avoir répondu.

la première commande renvoie "'not mounted"
la deuxième commande me renvoie qu'il me faut une version plus récente de e2fsck (l'autre soir nous avions eu le même problème)

voici ce que renvoie l explorateur quand je clique sur le disque dur .

Error mounting /dev/dm-0 at /media/mint/3e1290b7-202f-491d-a05c-1eaef5305bf7: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/dm-0" "/media/mint/3e1290b7-202f-491d-a05c-1eaef5305bf7"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/mapper/mint--vg-root,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.
