A hard disk expansion apparatus includes a printed circuit board (PCB), a connecting finger, and a signal expander. The connecting finger and the signal expander are both positioned on the PCB. The connecting finger receives a group of hard disk signals from a motherboard. The signal expander expands the group of hard disk signals into multiple-group of hard disk signals, and provides the multiple-group of hard disk signals to at least one hard disk. |
