Simple Volume VS Primary Partition

The simple volume is dynamic storage which functions as a primary partition in Windows NT 4.0 and its older versions, can only be created on a dynamic disk.

The primary partition is a partition which can be used to boot an Operating System, can only be created on a basic disk with MBR or GPT partition table under all Windows systems.

Hence, simple volumes are based on dynamic disk while primary partitions are based on basic disk. To convert simple volume to primary partition, it equals to a switch from dynamic disk to basic disk.

How to Convert Simple Volume to Primary Partition

As we know, Windows Disk Management allows users to convert a basic disk to dynamic disk, but you cannot convert the dynamic disk back to basic disk directly unless you delete the volumes first. That is to say, as long as you choose Windows Disk Management to convert to basic disk, you must create a hard drive backup if data is concerned.

It's not available to Convert dynamic disk to basic in Windows Disk Management as shown below.

In this case, third-party disk management alternative software - EaseUS Partition Master will save your energy to change the simple volume to primary without deleting or removing any data. It provides a "convert to basic disk" feature to complete this task with easy clicks without any data loss.

3-Step Tutorial to Convert Simple Volume to Primary Partition with Easeus Partition Master

The following is a step-by-step instruction for you to try with dynamic disk converting software - EaseUS Partition Master Professional.

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

Step 2. Select the disk that you want to convert, tight-click it and choose the conversion option:

  • Basic to Dynamic: right-click a basic disk and select "Convert to Dynamic".
  • Dynamic to Basic: right-click a dynamic disk and select "Convert to Basic".

Step 3. Click "OK" on the pop-up notice window and you will add this conversion to the pending operations.

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

0:00 - 0:21 Convert Basic to Dynamic Disk; 0:22- 0:48 Convert Dynamic to Basic Disk.

The program will automatically convert all these simple volumes in the dynamic disk to primary and logical partitions.

Must-read tips:

1. If your dynamic disk is an MBR disk and there are more than 4 simple volumes, after the converting, you'll get 4 primary partitions, and the rest will become logical partitions. When you haven't reached the upper limit, you can use EaseUS Partition Master to convert logical to primary. But if your dynamic disk is GPT, all simple volumes will turn into primary partitions after processing the above steps.

2. This Convert to basic disk feature can only work on a dynamic disk with simple and mirrored volumes. Spanned volume, striped volume in the dynamic disk are not supported.

3. All other operations are not available when "Convert to basic disk" is applied.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives. You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
