  We prove the saturation of a generalized partially hyperbolic attractor of a
$C^2$ map. As a consequence, we show that any generalized partially hyperbolic
horseshoe-like attractor of a $C^1$-generic diffeomorphism has zero volume. In
contrast, by modification of Poincar\'e cross section of the geometric model,
we build a $C^1$-diffeomorphism with a partially hyperbolic horseshoe-like
attractor of positive volume.
