The sensor will notice already the start of the move. The notebook will
then normally be accalerated with 1G as it simply goes into a free fall.
If the heads are then moved away from the disks and the notebook hits
some ms later ground, it does not matter any more if this event takes
micro- or milliseconds as the heads are already out of the danger zone.
