If the snow is deep enough for you to loose traction then you should disable the DSC as that will cut the engine power and stop you from being able to use the tyre sidewalls from getting grip by swinging the steering wheel from lock to lock. DSC thinks you are going to crash the car when you start doing that sort of stuff, but actually in sand, mud and deep snow (sort 0.5m deep not 5cm deep!) you sometimes need to twirl the wheel a lot. DSC also will not let you apply lots of power which sometimes you need to prevent bogging down.
What I would recommend is that you only disable HDC when you are travelling "normally" in snow and as soon as you get to an incline or decline then re-engage it, left on all the time it can eat up sets of brake pads very very quickly.
By the way, here in supposedly snowy Central Scotland it is +5 and there isn't a sign of snow anywhere except the very tops of the highest mountains, I'll be outside tidying up the garden this afternoon! It must be a tough life living in the SE with such horrific extremes of weather, one minute droughts and seering sunshine the next, 2cms of snow bringing the place to a grinding halt........................
