Impossible de partionner mon DD pour passer a

Bonjour,


Je vous explique ma grosse galere depuis 22h (il est 1h28...) je tente créer une nouvelle partition sur mon dd pour pouvoir installer windows 7
or au bout de 5 logiciels de partition sa ne veut toujours pas
j'ai plein de messages d'erreurs :
- "disk geometry error(s) were detected on this drive"
- " init failed partition's drive letter can be identified"
mes deux partitions (C pour windows et E pour les donnés) sont considérés invalides je ne peux donc ni les redimensionner ni en créer une nouvelle ! ce qui fait que je n'ai aucune action possible
si bien que quand je boot sur le cd de windows 7 il ne reconnait qu'une seule partition ce qui fait qu'il va tout ecraser il faut que vous m'aidiez a reparer mon DD pour que je les partionne correctement !!

merci d'avance

cf : voici le rapport de partition magic
