Put more weight on the outside foot peg. This will get the tire to squat and get more traction in the hard packed. Also lean a little more to the outside too. This should all help going in and coming out ofn a hard packed turn.
I'm no professional and don't know the answers to your question (actually a beginning racer), but if you give a little more information concerning the problem, the people here might be able to help you out a little better.
