Clone Win 10 from external to external SSD drive error

Hi

I’ve just upgraded to v9 running on my Macbook Pro 2015, 15" and was attempting to clone win 10 on an external ssd drive to another external ssd drive (making a bootable win 10 copy) though I get an error

(There was an error during the disk to disk clone. There may be a problem with one volume or the disks).

I did read that the std version will clone a bootable Win 10 from an external drive to another external drive. I’ve checked the parameters…format MS-DOS (fat)…Scheme GUID Partition Map…I’ve erased and redone the drive and the source drive works fine when I boot from it on my Mac.

Or do I need the pro version?

The pro version won’t help with this issue. What was the error you were getting?
