Abstract
A shock and vibration resistant hard disk drive has a plurality of fluid damping isolation devices disposed between the drive and a supporting frame. The isolation devices are capsules containing either gasses or liquids enclosed in a flexible membrane. Variation of fluid properties such as density, viscosity, and pressure allow for custom tuning of the vibration and shock performance.
