Hard drive retention mechanism

A system comprising:

• a chassis for receiving a data storage device;
• a housing for the data storage device, wherein the housing has at least one protruding portion located on the exterior of the housing and an opening in the housing;
• at least one receiving portion on the chassis, wherein the at least one receiving portion aligns with the at least one protruding portion, wherein the at least one protruding portion can be coupled with the at least one receiving portion to secure the housing to the chassis, wherein one of the receiving portions is a tab fixed to the chassis having a slot with a slit-like opening for allowing expansion of the slot to fit a diameter of one of the protruding portions to provide an interference fit between the receiving portion and the protruding portion;
• and
• a member resiliently fixed to the chassis, wherein the member can be aligned and coupled with the opening in the housing when the at least one protruding portion is coupled with the at least one receiving portion.

A system comprising:

• a chassis for retaining a hard disk drive;
• a housing for the hard disk drive, wherein the housing comprises a plurality of pins and an opening on one or more sides of the housing;
• a plurality of slots having diameters not larger than the diameters of the plurality of pins, the slots on the chassis for receiving the plurality of pins, wherein the plurality of slots couple with the plurality of pins, at least one of the slots including a slit-like opening for allowing expansion of the slot to fit a diameter of one of the pins to provide an interference fit between the slot and the pin;
• and
• a spring plunger on the chassis, wherein the spring plunger inserts into the opening,
• wherein the coupling of the plurality of pins with the plurality of slots and the insertion of the spring plunger into the opening secures the housing to the chassis.
