Bonjour,

ce disque USB n’est plus reconnu, ni par blkid, ni par sfdisk.
la commande hdparm indique:

$sudo hdparm -I /dev/sdb

et la commande gpart:

#gpart /dev/sdb

Begin scan...

* Warning: read error (EIO) near sector(62), skipping...
End scan.

Checking partitions...
Ok.

Guessed primary partition table:

et gparted la désigne (/dev/hdb) mais mouline en vain.

Ce disque est-il récupérable? (j’en doute car fdisk et sfdisk échouent à le reconnaître). Mais mon ignorance abyssale m’incite à vous poser la question avant de le jeter.
Merci pour votre compréhension

Bizarre , le disque répond aux commandes de smartctl et n’indique pas de souci. Premier candidat au problème, le cable de connexion USB, essaye un autre cable voir un autre boitier USB, mais ces p…ns de disque WD sont je crois complètement soudés au controleur SATA/USB. Essaye qd même un cable différent.
Sinon regarde ce que disait dmesg et autre, en clair

sudo lsblk -o NAME,SIZE,MODEL
sudo fdisk -l /dev/sdb
sudo dmesg | tail -100

mais gpart donne déjà une idée :-/

oui ça sent le sapin.
