Thanks to everyone who posted replies about my problem. Further careful checking has shown that my live Hub is working OK , and it is the attached 500 Gb WD5000AAD storage which is faulty. It is not seen by the Live Hub or when attached to my computer. I think the FAT or partition needs fixing. I passed it to a friend who knows about fixing discs which have gone AWOL .I’m not optimistic that the disc can be made readable without losing the data.
Sorry my enquiry got posted to the WDlive hub forum, It should have gone to the USB disc forum.
I close my dialog for now.
