Presumably the computer is a desktop, not a laptop?

If it's a laptop:
a: make sure it is connected to mains power
b: try selecting a USB port as near as possible to the power adapter cable connection point
c: as mentioned, if you have a 'Y' cable, connect both USB connectors to the computer (my 2016 Audiophile doesn't have a 'Y' cable).

Alternatively, make sure the drive can mount successfully on a separate computer.

On the computer with the issue, connect the USB drive, then go to Control Panel > Device Manager and see if there is any small yellow exclamation marks next to any devices in the list, indicating that the device is 'available' but not correctly recognized (maybe a driver error etc)
