Hi Wez1344,
Many thanks for taking the time to reach out to the Community, welcome!
I am sorry that this error has popped up on your screen, I was able to run some preliminary tests and I have been able to see that your downstream power levels and hard drive aren't looking the best.
I would mention that this would most likely need an engineer and a box swap if the engineer isn't able to resolve the issue there and then. I would like to arrange an engineer to come out and adjust the signal levels on the cabling and also take a look at the hard drive. I've sent you a 'Private Message'. You can find this at the top right of the page, purple envelope 
Speak to you soon.
Ben
