nooo... don't point people at very limited and deliberately 
hidden/undocumented commands. This command can't handle image chains 
(which means it will produce complete garbage if you point it at some 
file corresponding to a snapshot).

I can't undo this well meant (but unfortunately not ideal) advice, but 
please don't go this way.

VBoxManage clonehd <src> <dst> --format RAW

is the proper way, and documented.
