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.

  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.
