Close, but not quite. Consider MDRate = 50. This means everything does half damage, so you want effective HP to be twice the original. By your formula however, it only comes out as 1.5x original.
This is like those problems where, if you take an original price, mark it up 20%, then discount it 20%, the end price is actually 4% lower than you started with, since the second 20% is taken out of a larger amount.
What you want is 100 / (100 - MDRate), although with fairly low values of MDRate the two expressions tend to be close.
