Why is my external hard drive beeping?

Yeah, I was doing some research and found that a single intermittent beep often means the drive isn’t getting enough power. Have you tried connecting it through a powered USB hub? Sometimes other devices can draw too much power, like your heater fan.

It sounds like your hard drive might not be getting enough power. Try switching to a different USB port or even connecting it to another computer to see if that helps. If it still beeps, it might indicate a failing disk—make sure to check if it happens on multiple devices.

You might be facing a major hardware failure, unfortunately. If it’s only three days old, though, definitely return it for a refund!
