LDM(Logical Disk Manager) MetaData Partition
LDM METADATA PARTITION
GPT GUID: 5808c8aa-7e8f-42e0-85d2-e1e90434cfb3
MBR partition ID: None
The LDM Metadata partition is a 1-megabyte hidden partition that stores the dynamic disk database, which contains information about all dynamic disks and volumes installed on the computer.

GPT GUID: af9b60a0-1431-4f62-bc68-3311714a69ad
MBR partition ID: 0x42
The LDM Data partition acts as a container for dynamic volumes. Individual dynamic volumes do not contain entries in the GUID partition entry array.

The location of the database is determined by the partition style of the disk.
- On MBR disks, the database is contained in the last 1-MB of the disk.
- On GPT disks, the database is contained in a 1-MB reserved (hidden) partition(LDM Metadata partition).

MBR에서는 LDM metadata를 저장하는 공간은 partition이 아니므로 표시되지 않습니다.
(bootice의 sector edit - unassigned space에서 data를 볼 수 있습니다)
GPT에서는 MSR의 첫 1MB를 차지합니다(Microsoft 문서의 그림과는 위치만 다름).
