1. A hard disk drive, comprising: an actuator arm to pivot across a disk about a pivot shaft and having a read/write head disposed at an end portion of the actuator arm to read data from the disk and to write data to the disk; and a crash stop to prevent the read/write head from being pivoted beyond an outermost position of the disk, the crash stop comprising: a housing coupled to a base of the disk drive and disposed adjacent to an outer circumference of the disk, wherein the housing includes a coupling body having a coupling groove; and a buffer member formed of an elastic material and forcibly coupled to the housing, the buffer member including a coupling protrusion that is forcibly coupled to the coupling groove and a contact portion that extends outward from the coupling body in a first direction, wherein the coupling body includes escape prevention portions that define an opening portion in the coupling body, and a distance between the escape prevention portions is substantially equal to a width of the contact portion and is less than a length of a longest side of the coupling protrusion.
