Dynamic disk 

A hard disk managed by Logical Disk Manager (LDM) that is available in Windows starting with 
Windows 2000. LDM helps flexibly allocate volumes on a storage device for better fault tolerance, 
better performance or larger volume size. 

A dynamic disk can use either the master boot record (MBR) or GUID partition table (GPT) partition 
style. In addition to MBR or GPT, each dynamic disk has a hidden database where the LDM stores the 
dynamic volumes' configuration. Each dynamic disk holds the complete information about all 
dynamic volumes existing in the disk group which makes for better storage reliability. The database 
occupies the last 1MB of an MBR disk. On a GPT disk, Windows creates the dedicated LDM Metadata 
partition, taking space from the Microsoft Reserved Partition (MSR.)
