I have a portable hard drive that plugs into my USB port... My port does not supply enough power to power the hard drive. The manual states I can use an AC Adapter which outputs 5volts, 800 or more milliamps, polarity negative on the tip. I am unable to locate such an AC Adapter. I have a 4.5 volt adapter which seems to work.
Question: Does anyone know if using a 4.5 volt AC Adapter rather than a 5 volt adapter will potentially damage the hard drive ?
