How to Change Dynamic Disk to Basic Disk Safely and Easily

Updated on Aug 11, 2019 by Tracy King to Partition Master

This post shows you two ways to convert dynamic disk to basic disk: one is using EaseUS partition manager software to convert dynamic disk to basic without losing data under Windows 2000/XP/Vista/7, and Server 2000/2003/2008; and the other is using Disk Management tool on Windows to do it by deleting all the volumes.

There are two types of disk storage types on Windows: basic disk and dynamic disk. Many users are dithering which one to choose before partitioning a drive. First of all, you need to understand the features of the two disk storage types. 

Basic Disk VS Dynamic Disk

Basic disk: It can be accessed by MS-DOS(Microsoft Disk Operating System) and all Windows-based operating systems. Basic disk usually uses the Master Boot Record (MBR) partition style that can contain up to four primary partitions, or three primary partitions plus one extended partition with multiple logical drives. It is the most often used, easiest to manage, and compatible disk type with Windows.

Dynamic disk: It provides the features that basic disk does not. For example, creating volumes that span multiple disks (spanned and striped volumes) and creating fault-tolerant volumes (mirrored and RAID-5 volumes). Dynamic disk allows users to create up to 2,000 volumes on a system. It offers greater flexibility to manage volumes without having to restart the computer. However, it’s only compatible Windows 2000/XP/Vista/7/8/10, and various versions of Windows server systems.

There are vast differences between basic disk and dynamic disk in the aspects of operating systems, volumes capacities, disk space, number of partitions, etc.. You can choose the one more suitable and also you can convert one type to another with some ticks. 

Is It Possible to Convert Dynamic Disk to Basic Disk

The basic disk can be directly converted to a dynamic disk using the Windows disk management tool in the supported system without data loss. Nevertheless, converting a dynamic disk to a basic disk is nor permitted with the disk management on windows, because dynamic disks are attributes that are better than basic disks. And the conversion is irreversible.

If you must convert the dynamic disk to the basic one, you have to delete all the volumes and data on the dynamic disk, which is the last thing you want to see. Then, is it possible to convert dynamic disk to basic disk without losing data? Luckily, the answer is YES with the help of reliable third-party software. Continue reading and see the how-to tutorials. 

How to Convert Dynamic Disk to Basic Disk Without Losing Data 

As said before, if you want to use the Windows built-in disk management to convert dynamic disk to basic, you need to delete all the volumes on the dynamic disk. Now, with the help of EaseUS Partition Master, you can do it directly and keep all the volumes intact without any data loss.

After EaseUS Partition Master applies these changes, you will see the dynamic disk has become basic disk in Windows Disk Management. And then you can use "Resize/Move partition" feature to resize partitions on the basic disk. (Tips: It is important to back up data before resizing partition because nothing is 100% secure.)

How to Convert Dynamic Disk to Basic Disk with Disk Management

If you want to try a free solution and use the disk management on Windows to convert dynamic disk to a basic, you can do it within three steps like demonstrated below.

To convert a dynamic disk back to a basic disk with disk management, you must delete all volumes, which means the data will be erased permanently. Make sure you back up all the data you want to keep before proceeding.

Step 1. Back up all volumes on the disk you want to convert from dynamic to basic.

Step 2. In Disk Management, right-click each volume on the dynamic disk you want to convert to a basic disk, and then click "Delete Volume" for each volume on the disk.

Step 3. When all volumes on the disk have been deleted, right-click the disk, and then click "Convert to Basic Disk".

To convert dynamic disk has mirror volumes, you need to break mirrored volumes before you can delete them. And then convert dynamic disk to basic disk by repeating the Step 2-Step 3 in this part.

Right-click "My Computer" and choose "Manage" -> "Storage" -> "Disk Management", right-click the mirrored volumes and choose "Break Mirrored Volume" to break mirrored volumes or choose "Remove Mirror" to remove the mirror. If the boot/system partition is on the mirrored volumes, you can only choose "Remove Mirror" to remove the mirror. Please backup your important data before this operation. After choosing "Break Mirrored Volume" or "Remove Mirror", the mirrored volumes will become simple volumes. Then, you can delete them through right-click shortcut.
