The head actuators automatically park the heads on every occasion there is power cuts so that the platters won’t crashed to head actuators. There is no way that power cuts will cause your hard disk bad sectors but having a bad power supply can fail your hard drive because it will surge the circuit board of it and may fry the motor.
A cheap power supplies do not kill hard drive even slowly killing it. That is a myth. Like any other power supply, when it send and surge the hard disk the disk will be instantly kill.
