- Subject: disk 4 TB perte partionnement GPT/ext4
- Date: Sun, 25 Feb 2024 15:51:55 +0000
Bonsoir,
J'avais configuré un disk de 4 Tb en GPT puis un partion ext4 dessus.
Disque dur interne WD Red Pro NAS 3,5
Dans un NAS avec openmediavault.
Je viens de m'apercvoir que les données qui sont dessus, ne sont plus accebibles
sur fdisk il y a un message qui indique:
''La partition 1 ne commence pas sur une frontière de cylindre physique.''
Pourtant je n'ai pas fais de dimenssionnement du ce disk juste utilisé toute l'esqpace disponible.
Je pose ma question au début car l'expication est très longue.
Est-ce que j'ai une chance de récupérer les données ?
Disque /dev/sdb : 3,64 TiB, 4000785948160 octets, 7814035055 secteurs
Disk model: 03FFBX-68MU3N0
Unités : secteur de 1 × 512 = 512 octets
Taille de secteur (logique / physique) : 512 octets / 512 octets
taille d'E/S (minimale / optimale) : 4096 octets / 4096 octets
Type d'étiquette de disque : dos
Identifiant de disque : 0x084fe09f
Périphérique Amorçage Début Fin Secteurs Taille Id Type

La partition 1 ne commence pas sur une frontière de cylindre physique.

Actuellement je suis en train de faire un testdisk pour tenter de recuperr les données
cela va durée des heures
