A case structure for portable hard disk drive includes a case integrally formed by bending a whole piece of sheet material to having a bottom, a top, a first lateral side, and a second lateral side portion. The second lateral side portion is formed by overlapping two lateral end portions of the sheet material. The case is provided at the same end of the bottom, top, and first lateral side portions with a perpendicularly inward extended stop flange each, and each of the stop flanges is further provided with an inward and perpendicularly projected hooking tab. A hard disk tray with a hard disk installed therein for receiving in the case is provided with retaining holes for engaging with the hooking tabs on the case. With the case integrally formed from one whole piece of sheet material, only one single mold is required and the scrap is largely reduced.
