For the first few days of use My new Hopper had no problems transferring shows from the Hopper hard drive to my EHD hard drive. The correct prompts come up and the transfer process begins but now after a few seconds I get a message titled "USB Device Transfer Error 855". "An error occurred while transferring events to your external device 1" I've tried several fixes so far. I did a cold reboot and the Hopper recognized my external hard drive. I transferred several shows from the EHD back to the Hopper hard drive with no problem. I have plenty of room available on my EHD. For the first few days I successfully transferred dozens of shows from the Hoppers hard drive to my EHD. Now ERROR 855. Would a dirt team member be of any help? Would calling Dish be of any help?
