A mounting apparatus includes an enclosure, a bracket for fixing a data storage device, and a resisting member. The bracket includes a base and a handle pivotably mounted to the base. The handle includes a pressing portion. The resisting member is pivotably mounted to the bracket. When the handle is rotated toward the base, the pressing portion of the handle presses a first portion of the resisting member to pivot the resisting member. A second portion of the resisting member extends through the bracket to resist against the enclosure.
