Brief introduction of dynamic and basic disk

Basic disk is a physical disk that can be accessed by MS-DOS and all Windows-based operating systems. It can contain up to 4 primary partitions or 3 primary partitions and 1 extended partition containing multiple logical partitions.

Dynamic disk is a disk that functions like the primary partition on a basic disk. However, it can split or share data between disks or between disks. For example, a dynamic disk can actually consist of storage space separated on two separate disks. Also, dynamic disks can replicate data between disks or between disks in the event of some disk corruption. This function requires more disks, but is more reliable.

Why convert dynamic disk o basic?

But for compatibility, most users still use basic disks. Usually, we need to convert dynamic disk to basic disk in Windows PC, there are the following situations:

☞ Install a dual system. Windows cannot be installed directly on a dynamic volume unless it was converted from a basic disk.

☞ Other aspects are incompatible, such as dynamic disk does not support FAT file system.

Free convert dynamic disk to basic via Disk Management (data loss)

As we all know, Disk Management can help users solve many disk problems. But Disk Management does not support converting dynamic disks containing volumes or partitions to basic disks, it only allows you to convert those disks that do not contain volumes or partitions. This means that you need to delete all volumes on the dynamic disk before converting the dynamic disk to a basic disk.

Step 1. Open Disk Management, right-click each dynamic volume and select Delete Volume. Repeat this until all volumes are deleted.

Step 2. Then right-click on the dynamic disk and choose “Convert to Basic Disk”.
