Recuperation disque crashed synology

#1 Post by fred31 » 26 Mar 2017, 10:03

Hello,
Un de mes disques a laché, marqué comme crashed dans le disqk manager de synology...
Disque démonté, quelques tentatives de récupération des secteurs deffecteurs (avec HDD regenerator) et TestDisk arrive a faire une analyse (en mode deep search).
Bilan, toutes les partitions sont tombées et j'ai ce résultat

Et là, mes compétences s'arretes... j'ai tatonné sans succès
- mettre la partition SYNO210 en primary boot => le syno considère que le disque n'est pas initialisé
- mette le md0 en primary boot et le syno 210 en primary => le syno considère que la table de partition n'est pas lisible
retour au point de départ ... toute aide est la bienvenue :)

Pouvez-vous fournir le fichier testdisk.log ? Cela permettra de voir le type de Raid utilisé (Raid 0, Raid 1, Raid 5).

euh ... il fait 1.4Go :)
le disque était en Synology Hybrid Raid mais sans aucune protection ni optimisation de vitesse : en fait ce disque faisait son volume tout seul. ça aide ? :)

Check the harddisk size: HD jumper settings, BIOS detection...
The harddisk (3000 GB / 2794 GiB) seems too small! (< 16 TB / 15 TiB)
