Resolve Windows Raid 1 and delete mirroring

A few weeks ago, in our article ” Setting up software raid 1 (mirroring) under Windows 10 ” we explained exactly how you can set up a raid 1 (mirroring) under Windows relatively easily .

Upon numerous requests, we will show you here how you can resolve an existing Windows Software Raid 1 and thus delete the mirroring . The whole process is through Windows Disk Management


possible. As you can see in the picture below, a Raid 1 with 2 hard drives is set up on our Windows 10 PC as drive R :.

Remove reflection ...

Via the context menu of the first data carrier you will then get the corresponding option

Remove reflection …

But before the reflection is deleted , the following query appears.

Remove the mirror of the volume

The exact query is:

Remove mirror
Removing a mirror that volume is deleted a copy of the volume data. The volume will no longer contain redundant data.
Choose a disk. 

Now you have to select the data medium from which the Raid 1 mirroring should be removed . In our example, we selected disk 2.

Before Windows 10 finally removes the raid mirror , the following security question appears .

Are you sure that the mirror should be removed

Only when your question

Are you sure you want to remove the mirror?

Answered with ” Yes “, Windows removes the software level .

ATTENTION: Removing the mirror (Raid1) will resolve the software raid. You should therefore be sure of the consequences of this procedure for data security!

Then the 2 disks in the Windows disk management look like this.

Raid 1 resolved

As you can see, disk 1 from Raid1 (partition R 🙂 is unchanged. It still contains all the data that was previously stored on the data carrier. Only the mirroring of the data on the data carrier 2 is missing and thus the duplication of the data is missing .

The data carrier 2 is thus free again and could be integrated again as an additional partition.
