I had a 2 TB disk with a unique volume (on one single partition), containing information.

You watching: New mirrored volume not available

I did include a brand-new 2 TB disk to be used as a mirror of the existing one. I got in the Disk Management tool to "add Mirror" but discovered that this choice was not available. The menu was disabled:


Add Mirror Grayed Out

First thing to check: the 2 disks to be offered have to be "Dynamic". Right-click on "Disk x" to "Convert to Dynamic Disk ...".

Next, to have the ability to produce a mirror, the mechanism needs some complimentary space to produce its very own booked partition on the disk. So, right-click the Volume of the disk with information to "Shrink Volume..." (Try initially via 1 Mb). Once the disk has actually been shrunk, the menu "Add Mirror..." becomes available.

Et voilà.

It does not issue if the disks are MBR or GPT.Once the volume shrunk, you will perhaps need to reboot.If you encounter an problem while adding a mirror, carry out a "Check Disk" (Properties > Tools > Check).If you can really not eliminate the error "DiskPart has referenced an object which is not up-to-date." although rebooting, perform an "Extend Volume" of 1 MB! (Sound silly, I understand...) and also then "Add Mirror".In my situation, while the disks were re-syncing, I did remove the mirror, did an "Extend Volume" to reuse the totality free area, and also was still able to perform an "Add Mirror".
