LDM: Fix for Windows Vista dynamic disks
This fixes the LDM driver so that it works with Windows Vista dynamic
disks which are subtly different to Windows 2000/XP ones.
The patch was needed to get a Vista formatted dynamic disk to be
recognized and parsed successfully.
Thanks go to Chris Teachworth for the report and testing.
