I am running Symantec Backup Exec 2010 R2 SP1 and am getting a job failed with exception 'failed to mount one or more virtual disk images' when trying to run a GRT application and file level backup of a hyper-V server. Both host and guest are running 2008 R2 SP1.

I only get this error on one particular type of usb external drive - WD 3TB Drives- my 1TB and smaller drives work perfectly.

I have been informed by Symantec that they do not support hyper-V GRT level backups to a GPT disk.
My confusion is that when initially inspecting the disk in disk management, even though it had a 3TB partition, it showed as MBR -   but I am aware that the maximum size for an MBR partition is 2TB.
I deleted volumes and converted to GPT (tested job, still failed) and back to MBR, and now it gives me two partitions, one 2TB, and one 750GB or so - however job still failing.

Does anyone have any pointers at all?
Many thanks in advance
