Excellent stuff!! Its now working 
Yeah i was using disk 2 as the one to move, and I should have been choosing disk 1 in the workflow!
It was a bit confusing as it said "system disk" for disk 0 in the workflow and i presumed this would have been the VMX files themselfs. So 0 would have been the vmx, hard disk 1 would be hard disk 1, then hard disk 2 would have been the one I wanted. As you rightly pointed out, harddisk 0 in the workflow is not actually the vmx file, it is actually hard disk 1, then hard disk 1 in the workflow was the one i wanted.
Thanks again for all your help.
