I welcome you sir and thank you for coming to us. Sometimes just restart helps.

Sometimes trying different usb port. But just follow all the steps in provided guide and you should be fine.

Please, keep us posted!

could be the hard drive itself tbh don't buy cheap ones if that's the case.

I'd check the power on the external hard drive too. Make sure it's all plugged in to a working outlet and make sure it's switched on, and check all the plugs to the Xbox One to make sure it's hooked up properly. If it's still not connecting, it might be
an issue with the hard drive itself. The Xbox One should pick it up and register it being there if it's hooked up and turned on. Good luck, I hope it fixes soon!
