@nh302 : I'm glad you were able to solve your problem, however, when there is a failure of an internal HDD, the PVR will often still boot and function as a tuner box, but not be able to view existing recordings, or pause live TV or start new recordings...
Not necessarily. I can’t confirm for certain with this 4K box, but in previous generations if you opened up the box and disconnected the hdd from the motherboard, it would work fine as a tuner only with no glitches or odd behaviour.
Lastly, I called Rogers one last time on Thursday. Got an experienced tech on the line, which was a pleasant surprise, and only had to say two sentences before he said the hdd was at fault. Common problem with this 4K pvr box after 3 to 5 years with Toshiba HDD, and would cause it to act quirky with all the symptoms described plus more depending on how badly the HDD was failing.
Made the call to Rogers because they advised to call when the box was frozen so they could look at the diagnostics.
With the number of partitions created, I wouldn’t be surprised if the 4K pvr box was using very small partitions to store some boot data, guide data etc. And a tiny partition to catalog recordings and the large partition for the recordings themselves. This box is made by technicolor, and not Cisco like previous models.
Problem is resolved and I am going to bow out of this this thread. I did hands on troubleshooting to back up my progress and comments till final resolution.
@nh302 - Do you mind sharing which drive you purchased (make and model)? I'm the OP and the problem for me at least hasn't reappeared since deleting all my recordings and not filling it up to capacity like before. It would be good to know what drives are compatible for future reference in case the time comes where I need to replace it. Thanks.
If you don't get a response from @nh302 , the WD "Purple" drives are usually recommended for this sort of service. Here's a thread on Digital home regarding the HD 9865 box which might come in handy, even though it's not the exact same box.
I haven't done this myself. There are a couple of links in post 1 of that thread that go into great detail on how to do this on the 9865. I'm assuming those instructions don't help with the 4K? Not very many people have had to do this on the 4K box, hence the lack of knowledge on the topic. Let's hope someone gets back to you if those links don't help.
