How to Convert Dynamic Disk to Basic Disk Without Losing Data

This is very much easy to convert a basic disk into dynamic disk in Windows operating system using Windows UI itself. But once you done and want to revert, i.e convert dynamic disk to basic disk without losing data, I believe If you landed here, you know the real scenario how difficult it is. Windows doesn’t have any UI or command line to convert dynamic disk to basic disk without losing data.

If you visit the Microsoft support site they suggest you to first backup all your data in another hard disk then delete all the partitions in current hard disk (which you want to convert into basic disk/static disk), only then you can convert dynamic disk to basic disk. That means if you follow them you have to arrange an other storage device otherwise be prepared to lose all your important data. How frustrating this is Windows made basic disk to dynamic disk conversion so much easy, you can do it in just couple of clicks but the dynamic disk to basic disk conversion so difficult specifically if you are not ready to lose your data.

Do not worry, there are many third-party tools that let you do your task very easily. Using any of those tools you can convert dynamic disk to basic disk without losing data in just couple of clicks – you’ll not need to arrange another storage device to backup your data and to delete partition in current dynamic hard disk. Before we proceed to learn how to convert dynamic disk to basic disk without losing data using partition manager tools, we first should have some knowledge about these disk types – i.e what are dynamic disk and basic disk/static disk and the advantages & disadvantages over each other?

What is Basic Disk/Static Disk :

A basic disk uses primary partitions, extended partitions, and logical drives to organize data. A formatted partition is also called a volume (the terms volume and partition are often used interchangeably). In this version of Windows, basic disks can have either four primary partitions or three primary and one extended partition. The extended partition can contain multiple logical drives (up to 128 logical drives are supported). The partitions on a basic disk cannot share or split data with other partitions. Each partition on a basic disk is a separate entity on the disk.

The following operations can be performed only on basic disks :

  • Create and delete primary and extended partitions.
  • Create and delete logical drives within an extended partition.
  • Format a partition and mark it as active.

What is Dynamic Disk :

Dynamic disks can contain a large number of dynamic volumes (approximately 2000) that function like the primary partitions used on basic disks. In some versions of Windows, you can combine separate dynamic hard disks into a single dynamic volume (called spanning), split data among several hard disks (called striping) for increased performance, or duplicate data among several hard disks (called mirroring) for increased reliability.

The following operations can be performed only on dynamic disks:

  • Create and delete simple, spanned, striped, mirrored, and RAID-5 volumes.
  • Extend a simple or spanned volume.
  • Remove a mirror from a mirrored volume or break the mirrored volume into two volumes.
  • Repair mirrored or RAID-5 volumes.
  • Reactivate a missing or offline disk.

Now let’s start to see how to convert dynamic disk to basic disk without losing data using partition manager tools. There are so many such tools over Internet but here I’ve mentioned two of them I find myself easy to use.

  1. AOMEI Dynamic Disk Manager Pro Edition
  2. EaseUS Partition Master Professional

The free/trial version of these tools doesn’t include functionality to convert dynamic disk to basic disk. You have to buy one (or find somehow over internet), before you buy must confirm checking the feature table if it include the feature to convert dynamic disk to basic disk.

Steps to Convert Dynamic Disk to Basic Disk Without Losing Data :

Watch the video tutorial for better understanding :

In case you didn’t liked the video follow the steps below :

  • Get any of the Disk Manager tool from listed above
    (Here I’m using AOMEI Dynamic Disk Manager Pro Edition for demo purpose)
  • Install the tool in your system

    1. Select the disk you want to convert
    2. Click on “Convert to Basic Disk”

  • Click ‘Yes’ if popup to ask you to convert after reading the message carefully in popup window.
  • Tool will ask you to restart the system to complete the process. Save your other opened document(if have) before you allow to restart.
  • While the system restart tool complete the remaining task of converting dynamic disk into basic disk. You don’t need to do anything.
  • Once the System restart successfully, You are done !!
