I'm trying to ensure that robocopy does verification after it copies

I've seen plenty of post from folks saying that it does, but I have
yet to see any sort of documentation for this.
I'm looking for something definitive (preferably from MS). I've been
all over the MS Knowledge base, msdn, technet,
& mvps.org (to name a few), but no solid confirmation. I've reviewed
the .doc for robocopy which is included with
the resource kit download...nothing.

Any help with this would be greatly appreciated.
