You weren't able to restore the data with something like Recuva?

I did something similar but not with Replicator, I was erasing an external USB drive preparatory to using Replicator to copy an internal drive to it, and somehow erased the internal (source) drive instead, Shift-Del on the root folder! Recuva brought all the data back except for one photograph. Don't know why it didn't get that.
