Of course it can't prevent shocks :-) It can try to minimalize the impact of a shock though. I am a happy owner of a X40. Just got it, so it still runs XP. The software parks the heads of the disk if it detects movement. It is very sensitive and quick so I believe it can protect the harddisk if the notebook gets dropped during use. In a car the software adapts to the usual bumps so the notebook is still useful :-) The windows software shows a picture of the notebook in 3D which tilts if you tilt the actual notebook. Neat :-)
