This is a clean installation of Windows 10 Home, and I want to set up a software mirror on one of my disks. The Add Mirror option is completely gone, not just grayed out but completely missing from the right mouse button menu. I had no such issue with Windows 7 and the same drives.

I have a combination of Basic and Dynamic Disks, sizes between 1 and 4TB, and a 4TB drive that I want to use as a mirror. None of the drives, basic, dynamic, large or small shows the Add Mirror option.

I know about Storage Spaces, and unless that is the ONLY way to set up a software mirror in Windows 10, I am not interested in it. Does anyone have any ideas what's going on?

Hi Rastkos,

I'm using windows 10 enterprise, there is add mirror option in disk management when right click mouse, as below:

However, you are using windows 10 Home, it may not support this functionality, and remove "add mirror option" from Windows 10 Home version.

I also recommend you post this in windows 10 forum, as they should have more professional knowledge and you may get effective solution timely.

Best regards,
