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."

"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."
