So it's the C: and D: drive which do not show the proper size. This is most likely an issue with the partition table which might have not been updated properly. What usually solves this issue is to slightly increase the virtual disk size (by e.g. 1 GB) , then - if required - perform a rescan and expand the partitions from the disk management.

PS: Just saw your latest reply after I posted this one. Did you try to increase the disk sizes yet?
