Just that, the Windows server will happily chug along uncomplaining & spit out a .vhd file, or rather a useless corrupt file with a .vhd extension if a volume over 2TB is set to be imaged.
Would be nice if AT LEAST an error was logged & the image failed, would be much nicer if a .vhdx file were produced which could actually be used. Or even some other format.
The 2TB limit on .vhd files is increasingly a limitation with modern large disks.
