Formatage disque RAID [Résolu]

[Gassonline]

Bonjour,
Je souhaite réutiliser un disque 2,5" de 750 Go sur un Mac mini.
Ce disque est sorti d'un Mac Mini Serveur. Il est donc formaté en RAID1
Je tente d'éliminer cette partition sans succès. Je peux juste la formater
Il y a t-il une manip particulière?
