PURPOSE: A hard disk selecting device for the multi-user operation is provided to selectively apply a few OS(Operating System) to one computer equipping with a few hard disks, and to construct an independent use region by operating only a switch installed to a computer case if a few users want to use one computer. CONSTITUTION: A hard disk selection switch selects one from the hard disks. A hard disk selection control logic(70) controls the power supply of the selected hard disk by receiving a selection signal from the hard disk selection switch. The hard disk selection control logic operates the power supply connectors(21a-23a) matched with the hard disks, a hard disk selection switch connector(30a), an operation indicating light connector(40a), and a main board power on/off connector(50). If the hard disk selection switch is selected doubly, the hard disk selection control logic cuts off an input signal to an open state by connecting the switch relay input between the hard disk control logic and the main board power on/off connector with the hard disk selection switch.
