A disk drive includes an enclosure that has a breather port therethrough. A first labyrinth path may be disposed inside the disk drive enclosure, in fluid connection with the breather port. A second labyrinth path may be temporarily disposed outside the disk drive enclosure, in fluid connection with the breather port. An alternative gas such as helium may be allowed to bleed out through the second labyrinth path during a period of servo track writing. The second labyrinth path may be removed after servo track writing.
