segun wikipedia ( y le creo ), tienen esos filtros para igualar la presion y humedad interna con la externa "The air filters on today's hard drives equalize the atmospheric pressure and moisture between the hard drive enclosure and its outside environment." http://en.wikipedia.org/wiki/Hard_disk_failure "The HDD's spindle system relies on air pressure inside the enclosure to support the heads at their proper flying height while the disk rotates. An HDD requires a certain range of air pressures in order to operate properly. The connection to the external environment and pressure occurs through a small hole in the enclosure (about 0.5 mm in diameter), usually with a carbon filter on the inside (the breather filter, see below). If the air pressure is too low, then there is not enough lift for the flying head, so the head gets too close to the disk, and there is a risk of head crashes and data loss. Specially manufactured sealed and pressurized disks are needed for reliable high-altitude operation, above about 3,000 m (10,000 feet). Note that modern commercial aircraft have a pressurized cabin, whose pressure altitude does not normally exceed 2,600 m(8,500 feet) - thus, ordinary hard drives can safely be used in flight." http://en.wikipedia.org/wiki/Hard_disk
