Why is the Dynamic Mirror showing failed?

When Dynamic Mirror shows failed on your PC, the following are the probable causes:

  • The Dynamic disk is offline – Dynamic disks allow volumes to have noncontiguous extents on one or more physical disks. If these disks are offline, they will be inaccessible.
  • Corrupted system files – System files are responsible for the services and processes running on the computer. Hence, your system’s performance can easily be affected if the system files are corrupted.
  • Damaged or compromised Dynamic disks – The dynamic disks becoming damaged can affect the volumes it operates and manages. So, you may encounter the Dynamic Mirror showing failed if the disk is damaged, preventing it from functioning correctly.
  • Power outage issues – Abrupt system shutdowns, power failure, or unexpected shutdowns during the mirroring process can cause the dynamic disk status to show failure.

These factors may vary on different computers. Nonetheless, we’ll discuss some basic steps to fix the issue and get the dynamic disk to work correctly.
