A 4200RPM drive has a smooth-polished glass or aluminum disk rotating at 25 metres a second. Quite lethal enough already ;) But still -- as far as the 72 bus goes -- aren't laptop hard drives mounted on little rubber suspenders and so on to minimise small shocks? And I know IBM has patents on technologies to prevent disk writes after a mechanical shock... Ryan
