Abstract: A computer disk drive dust protector is made in the form of an elongated wedge-shaped slot entry member which is inwardly tapered at the edges, so that insertion of the member into the disk drive slot causes the member to tightly wedge within the slot from end to end and from top to bottom, thereby preventing the entry of dust into the slot. A handle is attached to the rear edge of the slot entry member to facilitate the insertion of the member into the computer disk drive slot and to facilitate removal of the member from the slot when the computer is to be used. At least the portion of the device which enters into the disk drive slot is made of resilient plastic to resiliently hold the member in place in the disk drive slot.
