How to Convert Dynamic Disk to Basic Without Losing Data [2025]

If you want to convert a dynamic disk to a basic disk, you need to delete everything on a dynamic disk and then convert it back to a basic disk with Windows built-in tool or Command Prompt. This is frustrating for users who want to keep their data safe. Don't worry. This EaseUS guide will offer a professional dynamic disk converter that can help you convert dynamic disks to basic ones without data loss. Follow us and learn the step-by-step tutorial!

How to Convert Dynamic Disk to Basic Without Losing Data

It's safe to convert dynamic disk to basic using the following three conversion ways, which will theoretically not cause data loss. However, better safe than sorry. It's always a risk-free action to back up hard drive data before taking on unfamiliar activities. Now, you can convert  dynamic disk with three effective methods:

Method 1. Using EaseUS Partition Master (No Data Loss)

EaseUS Partition Master Professional supports converting dynamic disks to basic ones within simple steps. Download and install EaseUS Partition Master, activate it on your PC with a serial key, and follow the below guidelines to do dynamic disk converting.

Step 1. Install and open EaseUS Partition Master and go to Disk Converter.

Step 2. Select the disk conversion mode that suits your need:

• Convert Basic to Dynamic: change a Basic disk to Dynamic.
• Convert Dynamic to Basic: change a Dynamic disk to Basic.

Step 3. Select the target disk - Basic or Dynamic, confirm you've select the correct disk and click "Convert" to start.

Users can also apply EaseUS Partition Master to convert Dynamic disk to Basic with the abovementioned steps. This software can also resize partitions or copy the dynamic disk.

Only method one can promise you a safe and reliable dynamic-to-basic conversion. Other methods would ask you to delete all dynamic volumes, which would cause data loss. 

Method 2. Using Disk Management

Caution: Again, being different from converting to dynamic, when you try to convert a dynamic disk to basic, you'll be asked to delete all volumes first. This is why we emphasize the necessity of creating a backup beforehand.

Step 1. Open the Disk Management tool and right-click on the dynamic disk you need to convert or change to basic.

Step 2. Select "Delete Volume" for each volume on the disk.

Step 3. All volumes on the dynamic disk have been deleted, right-click on it and select "Convert to Basic Disk".

To avoid losing data, you can share these methods with more users online:

Method 3. Using Diskpart Command

Step 1. Open the command prompt diskpart window.  Note the disk number of which you need to convert to basic.

Step 2. Then, enter the following command and hit "Enter" after each command. (Note: 0 is the disk number, and 1 is the volume number.)

• list disk
• select disk 0
• detail disk 0
• select volume= 1
• delete volume
• select disk 0
• convert basic

Important: If multiple partitions are on the disk, you can continue to select the partitions and repeat the delete volume command until all partitions are deleted.

Step 3. After this, type: exit to finish the process.

Overview of Basic Disk and Dynamic Disk

Many of us are cooperating with a computer hard drive every day, and it's necessary to know some hard drive basics to make full use of it. For example, what does converting to a dynamic disk mean? 

There are two storage types of hard drives, namely the basic disk, and dynamic disk. As you know, dynamic disks come after basic disks, but now both are well supported by prevalent Windows operating systems, like Windows 10,8,7.  If you're interested in the main difference between the two items, here is a full explanation.

1. Number of volumes

• Basic disk supports only primary partitions, extended partitions, and logical drives. The number of primary partitions + extended partitions is not allowed to exceed 4.
• When you change a basic disk to dynamic, you can create volumes spanning multiple disks (spanned and striped). Though the recommended number is 32 or less, you can still build up to 2,000 volumes on a system. 

2. Flexibility for volume management

Dynamic disks can create fault-torrent volumes like mirrored and RAID-5 volumes, and most importantly, are compatible with all Windows OS from Windows 2000 to Windows 10.

To know the differences between the basic and dynamic disks, you can check the comparison table for more information.

If you are looking for additional information, the following post is what you need:

Why Convert Dynamic Disk to Basic?

Dynamic disks offer advanced features like disk spanning and fault tolerance but may not suit all users. Here are the primary motivations for converting to basic disks:

• Simplification and Compatibility: Basic disks are simpler and more compatible with various systems and devices.
• Deprecation: Windows no longer supports dynamic disks, recommending basic disks and Storage Spaces instead.
• Troubleshooting: Dynamic disks can cause issues with multiple bootable systems or compatibility problems, which convert to basic resolves.
• Data Management: Basic disks are easier to manage for users who don't need advanced features like RAID configurations.

Conclusion

In conclusion, converting a dynamic disk to a basic disk in Windows typically requires deleting all volumes on the disk, which results in data loss when using built-in tools like Disk Management or Command Prompt. However, third-party software such as EaseUS Partition Master offers a solution to convert dynamic disks to basic disks without losing data. This software simplifies the process by allowing users to convert disks directly, maintaining all volumes intact. 

Convert Dynamic Disk to Basic or Basic Disk to Dynamic FAQs

1. Can you convert a dynamic disk to a basic one without losing data?

The basic disk can be directly converted to a dynamic disk using the Windows disk management tool in the supported system without data loss. However, if you must convert the dynamic disk to a basic one, you must delete all the volumes and data on the disk with Disk Management. However, with professional dynamic disk converter EaseUS Partition Master, you have no problem converting dynamic disk to basic without data loss：

Step 1. Install and open EaseUS Partition Master on your Windows computer.

Step 2. Select the dynamic disk that you want to convert to basic. 

Step 3. Right-click it and choose Convert to Basic. Click OK on the pop-up window to add this conversion to the pending operations.

Step 4. Click the Execute 1 Operation button at the top-left corner and Apply it to convert dynamic to basic disk.

2. What happens when you convert to a dynamic disk?

Converting a basic disk into a dynamic disk is a semi-permanent operation. Once you convert a basic disk into a dynamic disk, you can not convert it back into a basic disk unless you delete every volume on the entire disk.

3. What is the difference between the basic disk and the dynamic disk?

• A basic disk is a conventional storage model that uses partition tables or logical drives to manage data on the hard disk. 
• A dynamic disk does not use partition tables but dynamic volumes instead of partitions.

4. How do I undo a dynamic disk?

Here are the basic steps:

Step 1. Open the Disk Management tool and right-click on the dynamic disk you need to convert or change to basic.

Step 2. Select Delete Volume for each volume on the disk.

Step 3.  All volumes on the dynamic disk have been deleted; right-click on it and select Convert to Basic Disk.
