Wrong Mirror Sync

[pfp72]

Hi....
I made the most stupid thing I could do:

I syncronized (mirror) folder "A"(on USB key) with "R:\" instead of doing the opposite.
Even if "Recycled" on delete is active, "R:\" is a virtual drive create using Vsubst, and I am not able to recover the deleted files.

I have been trying for the last three days with several recovery applications but I am not able to find what has been cancelled.

Please help!
