WHAT NO-ONE TELLS YOU ABOUT USB DRIVES
Finally got copy/move to work properly. Using a 500gb drive I found it must be formatted by the Humax box, formatting on a W10 PC is not good enough. When formatted by the box it seems reliable and takes less than 5 minutes to copy/move a 1 hour file. I am not certain why this is but looking at the drive ... Windows just formats the whole drive in one partition, Humax box formats in 2 partitions one of them being just 10gb, presumably as a temporary work area (10GB will hold an HD movie).
This is all the manual says about fomats ...
