Physical characteristics

There are two types of Sea Shield: The first version of the shield is made of two pieces. The top is made of metal and serves as physical protection for the electronics. The other half is mounted on the bottom side of hard drive, and is fastened with a metal hook to the electronics board with two Torx screws. The metal shield covers the electronic circuit and electronic cables leading to the hard disk drive motor and drive head. Below the metal shield, there is a layer of foam, which serves as the actual electrostatic protection. The second version of the shield is included on many models from the U series. This one-piece approach replaced the metal and foam with rubber. However, this version was a bit less intelligible as rubber is also a heat insulator and has been blamed for failures of aging drives.

Other purpose
