I checked the registry, all seem ok with MountedDrive.
But i just found something very interesting ? i did know before and don't know really it's the real problem.
Acronis TI 2011 home don't support dynamic drive and GUID partition table (GTP).
Seem like a have to install pack extention (+30$).
Acronis True Image Home Does Not Support Dynamic Disks or Disks with GUID Partition Tables (GPT) | Knowledge Base
My D:\ drive mounted in raid0 and my G:\ drive are a dynamique drive et GPT
So, i have two options here. Hard way and short way but risky...
1- Backup stuff and convert to MBR disk and never use dynamic drive and GPT again
2- buy the pack extention and take the risk that don't work
