I’ve had this external drive for a few months now and no problems. then all the sudden it starts not wanting to access the data. It kept doin the not responding bit. Then I noticed every time I unplugged the usb cable the power light on the front would shut off. So I took the enclosure apart to find the usb/power circuit board is fried. What type of connector is the direct to the HDD? And where could I get a replacement board?
