Quanto pode danificar a onda de energia hdd?

Question

Eu tenho 2 hdds que começaram a morrer lentamente (baixa velocidade, altos tempos de resposta, alto tempo de atividade, acumulando contagens do setor realocadas) em um período de uma semana. Pode ser por causa de sobrecarga de energia ou PSU com defeito? Eu suponho que a oscilação de energia seria apenas fritar, pode ser o problema com o desligamento repentino?
