Why is it that the external hard drive is connected and disconnected?

Sometimes, external hard drives are connected well, used well, and then cut off. Why is that?

I probably connected the external hard drive to usb.
It's because the USB power supply is unstable.
The computer sends usb power, but the external hard drive consumes a lot of power, so it doesn't work.
When I bought an external hard drive, there would have been a power cable.
You can connect the power cable and use it.
