This external HDD is an plug`n play device. This means that no special drivers are required.
But the HDD support an 3.0 USB standard. This means that an USB 3.0 provides 900mA. An USB 2.0 standard provide 500mA… so if your notebook supports only USB 2.0, you will need to connect the HDD to 2 USB 2.0 ports to ensure that enough power would be supplied.
