A disk drive includes a disk, and a head stack assembly (HSA). The HSA includes a preamplifier; an actuator assembly that defines an actuator arm; a load beam supported by the actuator arm, the load beam defining a registration feature. A flexure is coupled to the load beam, the flexure defining an opening that is centered on the registration feature and including a plurality of conductive formations. The conductive formations include a plurality of conductive flexure connection pads that collectively define a center point; a plurality of conductive traces to electrically couple the plurality of flexure connection pads to the preamplifier, and a conductive feature disposed away from and aligned with the center point, the conductive feature at least partially surrounding the opening within the flexure. A slider is coupled to the plurality of flexure connection pads for reading and writing to the disk.
