Abstract

A portable computing device having an outer housing, and internal hard disk drive and a shock damping mounting assembly is disclosed. Multiple outer dimensions of the portable computing device can be less than the width of the hard drive due to a diagonal arrangement of the hard drive within the overall device. The hard drive can comply with a standardized form factor, such as a 3.5 inch form factor. A mounting assembly located within the outer housing and coupled to the hard drive can include one or more components adapted to damp a mechanical shock to the hard drive, which components can be mounted to corners and/or edges of the hard drive. Mounting assembly components can includes a first stage spring comprising a finger geometry that provides initial damping of the mechanical shock and a second stage spring comprising an elastic block that provides final damping of the mechanical shock.

Claims
