Rsync deleted all my data!!! - Please help

[OrnithO]

Hi,
I have a big problem, I launched a script using rsync and the option -delete-before, however the destination folder was the wrong one. I noticed it only seconds after but it was still too late. In less than 5 sec rsync deleted over 200gb of data on my external hard drive... It is not in my Trash nor on the HDD trash but it's not possible that the data were ereased in less than 5 sec! (I dont know how rsync handle deletions.) I know I am really stupid =D> but is there a way to get back all my data (mainly HD movies in mkv, mp4 and some avi)

Thanks a lot for any help you could give me.
