Windows 10: Cannot create mirrored disks

I need to mirror two 2TB drives, including the C: drive with Windows. Neither Disk Management nor Storage Places provide any solutions. In Disk Management, right clicking Disk 1 shows most options grayed out, including New Spanned Volume..., New Striped Volume... and no option for New Mirrored Volume, which should be the solution and I only know that exists due to another Windows help site.Navigating a vast tree of Windows information, including Windows button, Settings, Storage, Advanced storage settings, Storage Spaces, Create a storage pool and Storage Spaces displays a message that states:

Disk mirror failed redundancy: Remove mirror or reactivate volume?

Hi,



Thank you for writing to Microsoft Community Forums.



The cause for Failed Redundancy would be that half, but not both halves, of a mirrored volume was imported. In Disk Management, the imported half of the mirrored volume receives Failed Redundancy status, while the disk that holds the
half of the mirror that was not imported receives Missing status. You can import the Missing disk at a later time to restore redundancy.



The solution for Failed Redundancy is to move all disks that span this volume to the new computer at the same time, and then import all of the disks together.



The complete solution is giving in the section A mirrored volume's status is Data Not Redundant from
Troubleshooting Disk Management.



You may also refer the section A dynamic disk's status is Offline or Missing from the above article and try the troubleshooting steps.



If you are still facing any issues related to Mirroring, then I suggest you to post your query in
IT Pro TechNet forums, where we have support professionals who are well equipped with the knowledge on Hard Disk Mirroring.



Hope it helps.

I have done that but it does not work as with all the other disks I had mirrored earlier.

Do you have other suggestions?

 

My Drive Turned Into Dynamic Disk ! Please Help me !!!

If you right click the Pen Drive do you get either of the options, 'Break Mirrored Volume' or 'Remove Mirror'?

To break a mirrored set, follow these steps:

• In Disk Management, right-click one of the drives in the mirrored set, and then choose Break Mirrored Volume.
• Confirm that you want to break the mirrored set by clicking Yes.
• If the volume is currently in use, you'll see another warning dialog box. Confirm that it's okay to continue by clicking Yes.

To remove a mirror, follow these steps:

• In Disk Management, right-click one of the volumes in the mirrored set, and then choose Remove Mirror
• In the Remove Mirror dialog, select the disk from which to remove the mirror.
  
• If the mirror contains a boot or system volume, you should remove the mirror from the secondary drive rather than the primary. For example, if Drive 0 and Drive 1 are mirrored, remove Drive 1 rather than Drive 0
• Confirm the action when prompted. All data on the removed mirror is deleted.
