I recently switched from Sagate’s OEM version of Acronis True Image called “Seagate DiscWizard” to Acronis True Image 2020. It resulted in the setup routine detecting the OEM version (which is according to Seagate’s Knowledge Base from 2013)
 VirtualDiskSetup.msi will work in Windows 10 yes, but according to Acronis support this driver is from Windows 8 and not officially supported in Windows 10 and end of life since 2013.
So how can this be resolved?
From an email to Acronis Support in which I described how I have done it:
so I have continued on this as circumstances changed a bit:
I decided to get an addtional SATA III controller to put in an empty PCIe slot I still had in my computer and put an SSD onto it.
So here is what I have done:
As the HDD in question was 6 TB, 4 spread across 2 partitons with the Seagate DiscWizard Extended Capacity Manager and the 2 TB accessible on the front of the HDD was the Windows 10 system disk, I have done the following steps so far:
1) I have tried True Image 2020 Clone Disk Wizard, but as the new SSD is 1 GB smaller than the HDD (due to the nature of SSDs), I got warning messages saying there might be the possibility that Windows cannot boot after the clone is done as the destination disk is smaller than the source.
Despite I answered twice to proceed anyway, after the 2nd confirmation, the Clone Disk Wizard window simply closed without any further message on the screen.
So I gave up on this and instead used the free version of EaseUs Partition Master and cloned the 2 TB Windows 10 partition of the 6 TB HDD to the 2 TB SSD.
2) After that, I added the cloned Windows installation on the SSD via EasyBCD manually to the Windows 10 boot menu.
3) I booted my PC into an old Windows 7 installation I still have and disabled the Extended Capacity Manager. then I went to the Windows own disk manager and removed the 2 TB partition and then used EaseUs Partition Master to remove the 495 MB recovery partition too as windows own Disk Manager would not because of “not enough free diskspace to perform operation”.
4) Then converted the undefined partition from MBR to GPT.
5) Opened the Seagate DiscWizard again. A notification window poped up stating “No Extended Capacity Partitions found, you can partition the disk using “Add New Disc” functionality.
6) “Add New Disc” —> Was able to create a full 6 TB GPT partition
7) Booted back into Windows 10 onto the SSD.
8) Opened Acronis , went to recovery, said disk from the previously backed up extended capacity “Disk” stored on my NAS, to the unpartitioned 5.55 TB disk. However after 40 minutes of waiting, no activiy on the disk even. So I aborted this try and now create 2 partitions with EaseUS Partition Master that are both 3 TB and try again but this time recovery from partiton to partition instead.
I hope this will work!
Not quite the way it was supposed to work and I still have no idea why the clone disk wizard of True Image 2020 left me hanging with no clue, but it is busy recovering now
