    Merci ! j'ai essayé toute les commandes et j'ai les mêmes sorties, celle ci est intéressante :

    sudo btrfs-find-root /dev/sdc1

    _parent transid verify failed on 30474240 wanted 28329 found 28333
    parent transid verify failed on 30474240 wanted 28329 found 28333
    WARNING: could not setup extent tree, skipping it
    Superblock thinks the generation is 28333
    Superblock thinks the level is 1
    Found tree root at 33505280 gen 28333 level 1
    Well block 33406976(gen: 28332 level: 1) seems good, but generation/level doesn't match, want gen: 28333 level: 1
    _
    je ne sais pas ce que cela veut dire, évidemment, quant à : sudo btrfsck --init-extent-tree /dev/sdc1
    je l’avais déjà faite elle échoue, voici des extraits des résultats (très long ! ) :
