Method and apparatus (thermal controller) for controlling a thermoelectric device to affect the temperature of an internal thermal zone in a hard disk drive to enable a first heat transfer from an internal heat transfer interface included in a thermal interface to an exterior heat transfer interface thermally coupling to the exterior of said hard disk drive, and applying to enable a second heat transfer from the exterior heat transfer interface to the internal heat transfer interface. The thermoelectric device may include the thermal controller. An external cover may include the thermal controller. The hard disk drive includes the thermal controller directing the thermoelectric device. Systems including at least one of the hard disk drives. Manufacturing these apparatus and these apparatus as products of these processes are part of the invention.
