I've also had the same issue where, out of nowhere, the message #788 has popped up asking if I want to configure my EHD for the new receiver. I've had the EHD plugged in for 5+ months and have NEVER unhooked it from my ViP622. (It is a Seagate, so anytime I've wanted to access it, I've had to reboot my ViP622 in order to wake it up (even since the L4.49 update); but, other than that, it's worked fine.)
My question is: if I hit "Yes", and accept the update, will it reformat my EHD and erase my archived recordings? The answer I received from customer service is "maybe". I was hoping that I could get better clarification than that.
(I checked the Household Key seq num, and it no longer contains all zeros. My guess is that this is the reason that the DVR no longer recognizes the hard drive.)
If anyone can answer my question, (or has an alternate solution), I'd appreciate it.
Same thing is happening to me, but it has only been a week or so since I hooked up my new EHD. I haven't unhooked it, or powered it down, but now I'm getting message #866 that says the EHD is configured to another receiver, and if I want to use it on this receiver I need to reformat and erase all archived events. I tried a soft reboot last night (didn't have much time to troubleshoot much) and it did not fix the problem. I am having a replacement receiver put in today, so I am just going to hold my breath that when I hook my EHD up to it that it will just say I need to allow this receiver access to the EHD......much as it did last week when I received my new POS refurb! Keep in mind that the EHD is used last week was a friends, so once I dumped it's contents back to the DVR, I bought a new EHD....formatted it....and dumped it back onto it.
