I'm using Windows 7 x64 Ultimate. I have an existing 4TB disk with 3 NTFS volumes, a new 3TB blank disk, and I'm trying to mirror the volumes onto the new disk.
My Windows install is on an SSD which is Disk 0. The 4TB disk with volumes is Disk 1, and the new blank disk is Disk 2.
I can add a mirror successfully for the last volume, but when I try to add a mirror for the first volume I immediately get errors (see below).
Is there something I special I need to do to add a mirror for a volume other than the last one?
More info:
I opened Disk Management, right-clicked on the first volume on the existing disk, went to Add Mirror, and selected the new disk. The first time I did this I was prompted to convert the new disk to a Dynamic Disk, which I approved. Subsequently I got a message:
The operation failed to complete because the Disk Management console
view is not up-to-date. Refresh the view by using the refresh task. If
the problem persists close the Disk Management console, then restart
Disk Management or restart the computer.
I've refreshed disk management, restarted the computer, and converted the new disk to basic and back to dynamic, but I still get that error message.
Looking around for suggestions of a workaround, I saw a suggestion to use the diskpart command line tool.
Running diskpart from the Start Menu as Administrator, I did select volume 2 (the first volume I want to mirror) and then add disk 2 (the new disk), and received a somewhat similar error:
Virtual Disk Service error:
The disk's extent information is corrupted.
DiskPart has referenced an object which is not up-to-date.
Refresh the object by using the RESCAN command.
If the problem persists exit DiskPart, then restart DiskPart or restart the
computer.
A rescan appears to be successful:
DISKPART> select disk 2
Disk 2 is now the selected disk.
DISKPART> rescan
Please wait while DiskPart scans your configuration...
DiskPart has finished scanning your configuration.
but attempting to add the mirror again resulted in the same error.
The only similar report I found online was this:

Based on that I attempted to mirror the last volume on the disk to the new disk using diskpart, and that started successfully -- it is currently resynchronizing.
More Background:
In the course of dealing with a failing 3TB hard drive, I bought a replacement 4TB drive and installed it, then copied the partitions from the failing drive to it using Minitool Partition Wizard Home, and then removed the failing drive and was up and running again normally.
Now I've received a warranty replacement for the failing drive, and installed it, and now I'm attempting to mirror my partitions to it.
