Mounting apparatus for disk drive devices

A mounting apparatus for a disk drive device, comprising:

• a bracket having a first sidewall and a second sidewall, the first sidewall and the second sidewall each defining a first retaining hole at one end and a second retaining hole at an opposite end, the second sidewall having a protrusion protruding therefrom between the first retaining hole and the second retaining hole;
• an operation member slidably mounted on the second sidewall, the operation member forming a hook thereon corresponding to the protrusion of the second sidewall of the bracket;
• and
• a pair of rails mounted on both sidewalls of the disk drive device, each of the rails protruding two locating posts corresponding to the first and second retaining holes of the bracket,
• wherein the operation member is movable mounted on the second sidewall of the bracket between a holding position in which the locating posts of the rails are retained in the corresponding first and second retaining holes of the bracket and the hook of the operation member clasps the protrusion of the bracket, and a released position in which the hook is released from the protrusion.

A mounting apparatus assembly comprising:

• a data storage device assembly with a pair of studs on two opposite side faces, respectively;
• a bracket including a receiving cavity with a pair of side walls aside;
• a L-shaped slot formed in each of said side wall and in communication with an edge thereof;
• and an operation member moveably attached to at least one of said side walls, said operation member being moveable relative to the bracket at either a locking or a unlocking position, said operation member defining an L-shaped recess to receive the corresponding stud therein;
• wherein said data storage device assembly is assembled into the receiving cavity initially vertically and successively horizontally via the studs moving along the L-shaped slots, respectively, under a condition that the operation member is located in the unlocking position, and sequentially the operation member is moved from the unlocking position to the locking position to prevent the stud from moving backwardly along the corresponding slot.
