How to fix the issue – Windows 10 dynamic mirror showing Failed and get the data back? Lei’s see the possible culprits behind this issue and list the corresponding issues first.

Possible Reasons for Windows 10 Dynamic Mirror Showing Failed

When you run into dynamic volume’s status is Failed on Windows 10, you can take the following causes into consideration.

  1. The dynamic disk is offline.
  2. The file system is corrupt.
  3. The dynamic disk is damaged.

The three cases will lead to disk mirror Failed. To figure out which of them cause this issue, let’s try the following fixes one by one.

Fix 1: Make Sure the Disks Are Online

When dynamic volumes come with “Failed” status, make sure that the dynamic disks are Online first. So, if your dynamic disks are Offline, you should make it to Online.

To switch the mirrored dynamic volume to the “Online” status, you need to open Disk Management (by pressing Windows + R and then inputting diskmgmt.msc and clicking OK) right-click it and then choose Online.

If the mirrored dynamic volume has old data, bringing the disk online will not automatically restart the volume. So, restart the volume manually and then see if the volume returns to the Healthy status.

Fix 2: Repair File System

The corrupted file system is the second cause for Windows 10 dynamic mirror showing Failed. Why does file system corruption happen? File system can be damaged due to unexpected power loss, system crashes, and unsafe removal of the drive. So, take care of the mentioned cases when you are using your computer.

How to fix corrupted file system when the drive letter of the underlying volume comes back after trying Fix 1? You can run the Windows built-in tool that is CHKDSK or other reliable error-checking tools, like MiniTool Partition Wizard.

Run CHKDSK to Fix Corrupted File System

CHKDSK (Check Disk) is a good tool for the storage drive and you should run it every once in a while. Its main function is to mark the bad sectors and fix the file system errors to prevent data corrupted.

Since some Windows users reported that the underlying volume did not show up in File Explorer and the Properties option is unavailable, I would like to show you how to run CHKDSK via Command Prompt. Here is the tutorial.

Step 1: Open Command Prompt.

  • Type Command Prompt in Cortana’s search bar.
  • Right-click the best-matched result and select Run as administrator.
