Mounting apparatus for storage device

A mounting apparatus includes a frame, a resilient grounding piece and a fastener both made of conducting material. The frame includes an end arm, a first fixing arm connected to the end arm, and a second fixing arm pivotably connected to the end arm. Two pins protrude from an inner side of each of the first and second fixing arms, for correspondingly engaging in fixing holes of a storage device. The resilient arm is fixed to an outer side of the second fixing arm and includes a resilient arm bending away from the second fixing arm. The fastener is fixed to an inside surface of the resilient grounding piece and is pressed by the resilient grounding piece to extend through the second fixing arm and insert into the threaded hole of the storage device, to connects the storage device to ground cooperating with the resilient grounding piece.
