Accidentally did an "Erase" for My Passport for Mac! HELP!

I recently purchased a My Passport for Mac (USB 3.0) P/N: WDBLUZ0010BSL-03. 

I accidentally erased all the data in the portable harddisk! OMG! I know I am very silly but how do I restore it! I am panicking now.


If you mean the files and software that came included with your drive then you can download it from the link below:
