David, You can also open the physical Block I/O Protocol using OpenProtocol() with and attribute of EFI_OPEN_PROTOCOL_EXCLUSIVE. That will force all the partition and file system drivers and any other drivers off that handle so you can modify the disk layout safely. You have to check the return status to make sure your request for exclusive access was granted.
When you are done, you can call CloseProtocol() to release the exclusive access, and call ConnectController() for that handle to get the partition and file system drivers to discover the new layout.

If you need to do it from code gBS->DisconnectController() and gBS->ConnectController(). So basically you stop the driver from managing the handle and start it again.
