After BMR, dynamic volumes are not recognized by the operating system

To keep dynamic disks in a consistent state, the Windows operating system automatically synchronizes the Logical Disk Manager (LDM) metadata on each dynamic disk. So when BMR restores one dynamic disk and brings it online, the LDM metadata on this disk is automatically updated by the operating system. This may result in a dynamic volume not being recognized by the operating system and missing after the reboot.

To remedy this problem, when you perform BMR with multiple dynamic disks, you should not perform any pre-BMR disk operations such as cleaning, deleting volume, etc.
