ATI 2014 Prem - Cloning a secondary 2TB HDD (MBR) to a RAID1 4TB HDD (GPT)

Hello,

I've been using ATI for a couple of years now since I left (disgusted) with Norton Ghost. Have been using it flawlessly since I first started using the version that was available to Western Digital customers. I liked it so much, I went and bought the full version. Now, 3 version later, I'm at ATI 2014 Premium.

I have a machine, Windows 7. The main OS is on a 240GB SSD. A secondary 2TB (2x WDC Black HDD, SATA III, 64MB cache) hdd RAID 1 mirror is installed for data. I am upgrading to 2x WDC 4TB Enterprise series drives (SATA III, 64MB cache) in a RAID 1 mirror.

1) I cloned the existing 2TB RAID1 mirror to a locally attached 2TB backup drive (Successful).
2) removed the 2TB mirrored WDC Black drives, installed the 4TB RAID1 configured mirror WDC Enterprise drives and booted up the recovery media (Created from Acronis).
3) I attempted to clone the 2TB backup drive to the 4TB new RAID1 mirror. It recognized the new drive, but when I started the operation, it topped out at 2TB and said I was even 150MB short of completing the clone operation (the 2TB cloned drive was pretty full). So I cancelled it, and thought perhaps the Windows environment of ATI might have better luck.
4) I attempted to clone the 2TB backup drive to the 4TB new RAID1 mirror in Windows ATI. Again, recognized the setup just fine. And when I clicked proceed, said it had to reboot. Went into the non-Windows environment ATI and started cloning after a reboot. It showed it was cloning the disk (with no progress) for about 1 to 2 minutes and then just rebooted. No error was given on screen or in the logs and no action was taken.

I have tried creating the GPT in windows and formatting the 4TB mirror and then cloning (same result - was a long shot, but had to try).

I am using a MSI GD65 Gaming motherboard (z87 chipset). UEFI is supported, but since I am using a 240GB SSD as the OS/boot disk, I don't think I need UEFI... Or is that a mistake in thinking on my part?

Right now, I am reduced to doing a straight Windows copy from disk to disk (which I don't particularly like since there's always a risk of something getting missed, whereas the ATI product is more methodical in how it behaves with such a copy).

So, GPT and MBR is supported in ATI 2014 Prem I have come to understand. I understand the premium supports MBR to GPT cloning, so I must be doing something wrong. Does anyone have any thoughts on this to help?

thanks,

DB
