Somehow, by setting up a hardware raid 1 the LDM of both disks seems to have gotten corrupted. I removed the raid 1 and installed win again on one of the disks. The other disk wich contains all my data appears as foreign in my hdds list. I get the above error (INTERNAL Error - The disk group contains no valid configuration copies (C10000B6)) when I try to import the disk.
I'm pretty sure all the data is still on it, but I can't access it.
