And the blue area at the end of the dynamic disk is the LDM database. Its main function is to make Windows and other disk managers know the disk is a dynamic disk, not an empty disk. This partition table is not the same as the ones of a basic disk. The blue area at the beginning of dynamic disk is the MBR which saves the information of the partition table on the disk.

All this will be saved in the LDM database, which makes LDM database as the same important as partition table of a basic disk. The relevance of each dynamic disk allows you to see a 'Missing' disk shown in Windows Disk Management when you remove a dynamic disk from your system. This means that all dynamic disks are interrelated. The 1MB database records all the information of the volumes on a single disk, and also holds some related information on each dynamic disk, such as drive letter, volume label, the beginning sector of the volume, volume size, the file system of Volume, the current dynamic disk and so on.Įach dynamic disk will hold the mentioned information if there are several dynamic disks on your computer. What is the LDM database? LDM is an acronym of Logical Disk Manager, and it is a 1MB hidden database at the end of the dynamic disk.

The dynamic disk is a physical disk that manages its volumes by using the LDM database.
