Abstract: A disk drive has an internal breather filter that performs a filtration function while maintaining ventilation with an exterior of the drive. The filter circulates a gas between an interior and the exterior of its enclosure. The enclosure includes a first ventilation path for circulating the gas from the exterior to the filter, and a second ventilation path for circulating the gas from the filter to the exterior. In addition, a method of inspecting the filter and disk drive is disclosed. The method includes a compressing and decompressing step of compressing and decompressing the inside of the enclosure, a measuring step of measuring pressure in the enclosure, and a judging step of judging whether attachment of the filter is adequate on the basis of a value of the pressure measured.
