When i first connected my external hard drives i could access all of them at the same time even though they were connected to different hoppers. Now I can only access the external hard drives that are only connected to the hopper that the joey is linked up with at that moment even though i can access both hoppers DVR recordings at the same time. By accessing I mean they would appear on the DVR menu. Now only the EHDs that are connected to the linked hopper will appear on the DVR menu. Not a big deal but it was cool to be able to have access to all the EHDs connected to both hoppers at the same time without having to switch link ups with the hoppers. Also on a side note I just received the digital USB OTA tuner and it is working perfectly.
