Okay, I will admit total ignorance here as I don't have a Hopper setup. I may be invoking Murphy, but so far the SATA drive that came in my ViP 722k is still going strong after all these years. You may be the unfortunate victim of a series of infant mortality events with your drives.
I wish you better luck with your replacement Hopper.
