You should be able to do this using xxcopy (free from Pixielab and much much faster than almost all accelerated copy programs that I know) and the "shutdown" command in a batch file. You can even turn the batch into an executable if you like.
I'll have a fiddle this evening.
Just love batch files and some of the weird and wonderful things you can make 'em do for fun.
And of course, as someone said, there's always the brilliant Powershell (though it has a bit of a learning curve and a few traps)

PS: EaseUS works, but I don't like it.
