Why convert dynamic disk to basic disk in Windows 11?

Dynamic disks and basic disks are two different types of disk storage. Before knowing why converting dynamic disk to basic disk, we need to know the differences and compare dynamic disk vs basic disk:

• What is dynamic disk: Dynamic disks set up several segments called "volumes" to store data. When you change a dynamic disk, the information is recorded in the Logical Disk Manager.
• what is basick disk: When you initialize the hard disk on your computer, it is initially set up as a basic disk, which uses two forms of partitioning: MBR and GPT.

Although compared with basic disks, dynamic disks have some advantages (Click here to know more about dynamic disk vs basic disk). But for compatibility, our personal PCs use basic disks most of the time. Generally, we need to convert dynamic disks to basic disks in Windows 11 in the following situations:

☞  Install dual systems. Windows cannot be installed directly on a dynamic volume unless it is converted from a basic disk.
☞  The user converts a basic disk to a dynamic disk by accident, hoping to convert the dynamic disk back to a basic disk without damaging data.
☞  Other aspects are not compatible, such as dynamic disk does not support FAT file system.
