Retrieving data for time shift buffer !!!

Well after doing a factory reset , unplugged,change the hdd and everything else that I read it still says the same RDFTSB Which translated means your box is ?
Spoke to humax and they said it was probably the hdd or the sata lead or resistor
There Is power to the hdd and is running
Downloaded a update from humax site on to a usb stick and no change
Still the notification RDFTSB
HUMAX said buy another box !!!
