How can I get more power to my external hard drive?
If the drive still isn’t working, unplug it and try a different USB port. It’s possible the port in question is failing, or just being finicky with your specific drive. If it’s plugged into a USB 3.0 port, try a USB 2.0 port. If it’s plugged into a USB hub, try plugging it directly into the PC instead.
Does USB hub need power?
It is possible to use some USB hubs without a power supply, however, doing so may prevent the USB hub or certain high-power USB peripherals from operating. With USB peripherals that use power adapters, the USB ports on the hub are only used for data transfer and do not draw power from the hub.

Why does my hard drive not work with my USB hub?
My guess is you have an unpowered hub and your computer’s USB ports simply cannot supply enough power to the drive to make it work correctly. It’s easy to determine whether your current hub is powered or not. If it has an AC adapter connecting it to a wall outlet, it’s a powered hub (also known as an active hub).
