There is provided a head stack assembly (HSA) for a disk drive. The head stack assembly includes an actuator, a flex cable attached to the actuator, and a head gimbal assembly (HGA) attached to the actuator. The HGA includes a read head and a flexure attached to the read head. The flexure includes a dielectric layer and a plurality of patterned conductive traces on the dielectric layer. The flexure terminates in a flexure tail including a flexure tail hole. The flexure tail includes at least three fingers that project radially inward into the flexure tail hole. There is also provided methods of attaching the flex cable assembly to the flexure.
