Contained environmental control system for mobile event data recorder

A mobile event recorder data pack for use in a vehicle, the vehicle operating within a vehicle operating temperature range, comprising:

• a main processing module;
• a contained environmental control system for a hard drive, the system comprising:
• a housing for enclosing the hard drive;
• a thermoelectric module, coupled to and provided within the housing and for coupling to the hard drive, to transfer heat between the hard drive and the housing in response to an applied voltage in order to maintain a hard drive temperature within a hard drive operable temperature range, the vehicle operating temperature range including temperatures outside the hard drive operable temperature range;
• and
• a backplane system to interface the main processing module with the contained environmental control system.
