Mac accident formatted BIG drives format from Icy Dock External enclosure

It was not my day, accident formatted my Mac drives (it is external Icy Dock series http://www.icydock.com/goods_cat.php?id=131)It is an external case which holds TWO drives, I formatted to BIG (two drives into one big drive). My question is will Recuva or Pro will recover the Mac and formatted BIG format on my PC. Thank you.
