Claim:
A disk drive, comprising: a housing having a hub that defines an axis of rotation, a radial direction relative to the axis, and a maximum number of disk positions comprising at least two disk positions; at least one disk mounted to the hub but less than the maximum number of disk positions, such that a depopulated region having no disk is defined adjacent said at least one disk, said at least one disk being rotatable relative to the housing; an actuator mounted to the housing and being movable relative to said at least one disk, the actuator having a head for reading data from said at least one disk; a spoiler mounted to the housing and located adjacent the actuator; a wing extending from the spoiler adjacent said at least one disk in the depopulated region, the wing having leading and trailing edges, a longitudinal portion, a lateral portion extending perpendicularly from the longitudinal portion at the leading edge to define a rectangular leading edge, a void defined between the longitudinal and lateral portions aft of the leading edge, the trailing edge is open to the void such that the wing has a profile that is open and not solid; and the wing is circumferentially spaced apart from the head such that no portion of the head circumferentially overlaps the wing.
