Vibrations, Mortal Enemies of HDDs

Less dramatic but likewise common is the drumming on a somewhat fragile desk or bouncing of objects like bouncing balls of computer cases or simply hitting the case with the vacuum cleaner. This kind of scenario can cause vibrations that are the worst possible scenario for any HDD. If a drive can sustain a shock of 30-50G, the tolerance towards vibrations is usually only 1% of the shock tolerance. Typical values are in the order of 0.5-0.7G. It is happening every day. Transporting systems back and forth to LAN parties falls into the same category, in cases like that I always remove the HDD and transport it separately.
