I apologize immediately for posting this question here, but under great doubt that they will quickly answer me on the root code, if they answer at all because of the small number of participants (although the question has been posted there too). If you see fit, remove.
Actually the problem: there is a windows 7 Ultimate available, a bucket with a semi-raid. Two unequal in size disk 250 and 320 GB. How to transplant the current configuration without losing information on the raid (I think it most likely will not work as the disks are different) or lvm or something like that, the main thing is to have mirroring.
