Genetic drift is the random fluctuation of allelic frequencies through generations, that can be seen in small populations, not in bigger ones because the allelic frequencies are equals to the probability of picking a particular allele, it's the high number law.
But in the Hardy-Weinberg equilibrium, the population is infinite, there's an infinity of individuals, so the genetic drift doesn't occure.
So the genetic drift don't affect the Hardy-Weinberg equilibrium.
