Dcnc j'ai boote d'un USB stick comme tu me l'a propose. On change donc tous les sd puisque je me retrouve avec 2 USB sticks et deux disques durs, voila ce que j' ai fait:
ubuntu@ubuntu:/$ sudo sfdisk -luS

Warning: The partition table looks like it was made
for C/H/S=*/128/60 (instead of 1019/126/62).
For this listing I'll assume that geometry.

ubuntu@ubuntu:/$ sudo mount /dev/sdh1 /media/macle
Voila le resultat 🙁
ubuntu@ubuntu:/$ sudo ddrescue --force /dev/sdb /dev/sdg /media/macle/fichier1.log -n -R -d -i 10G
