[EXPERIMENTAL] DVR server on SHIELD Tube, etc

Looking at the nvidia forums it would seem there is a pretty pervasive issue with possibly poorly implemented storage access layer access In some apps causing the shield to drop the disk.

I don’t have anything but the DVR server installed on the system. I uninstalled plex. I wonder if The drive is being denied to protect it when it senses some kind of behavior it doesn’t like on the channels DVR server doing maintenance or something?

We were watching tv remotely last night before bed - The drive was disconnected this am. Same thing happened on the Sd card in the tube last week. Same overnight timing.

From an old nvidia forum post:
“ It's not a Nvidia problem. I have 3 Shields all with some form of external drive attached and none ever unmount. If you don't have ES installed, then most likely some other app that improperly implements the Storage Access Framework for full permissions (which is why ES cause external drives to unmount).”

It’s possible channels is doing everything perfectly but this seems to be suspect.

I think it has always been recommended to use a self Powered USB Drive ... Is yours powered by the USB Port ? If it is a Powered USB Hub will help. When recording and doing Comskip the Shield uses a lot of power.

Another thing you might try is enable developer options and do not let the Shield Sleep. "Stay Awake"

In the early days of the SHIELD we had lots of reports of disconnected drives, but it's not something I have heard of in the past year.

I would recommend a powered drive too. I think @HarperVision has some similar issues a couple months ago?

It’s interesting though that i had the same issue with an SD card, the power requirements for that should be pretty darn low. But the drive I’m using is USB powered. Is there a particular drive that is known to work super well?

I've used WD Easystore drives without issue. They're self-powered (directly plugged into its own power supply) and USB3.

Alrighty I have a self powered usb thang on the way hopefully it helps

Installed.. here's hoping it helps.. makes sense that it may. :slight_smile:

What is a usb thang ?

that's "self powered usb thang" to you!

I ripped apart the enclosure to my 1.5 TB GoFlex portable drive and just used this instead of the USB powered SATA adaptor that came with it.

Interesting i got to get one of those. I see various uses for it.

I have a few USB powered SATA cables around. They are super useful to have for working with older drives or archiving without enclosures. They are indeed super useful. It's cool they offer one with self power! This one works either way which is kind of nice to make it a bit more flexible.

I have been running the Channels DVR server on the TIVO Stream 4K since this thread began and have been very impressed. It makes a great little stand alone platform for my travel trailer so I have live TV channels, streaming apps player, a DVR server, and Player all in one box. I use a 256 Gb Flash and thats ample storage for how I use it. I did just notice a problem that I hadn't noticed before. When I delete a recording from Channels, it doesn't actually delete off the thumb drive. I figured it was a permissions thing because I also discovered that a couple file managers I put on the TIVO also would not delete the files. I can externally delete them however. Anybody got an idea what I'm missing here?

Strange. Does the DVR web UI Log tag show errors related to the delete?

Are they in the Trash?

I see no errors or a Trash folder. The files I deleted from channels are still in their original folder (TV) in my DVR folder. The reason I'm thinking its something besides the Channels App is because I tried deleting those files from file manager I installed on the TIVO (X-plore) and it also was unable to delete them. Then I copied a file from the thumb drive to the internal memory and the file manager was able to delete it there. I know Android has had idiosyncrasies in the past with external memory and this is what its looking like. I just haven't heard of any in current times. I can also delete the files externally over a wifi file manager (wifi file explorer) from my Mac. For whatever reason, the Android TV doesn't want to delete the files on the external memory. That's why I feel like I'm just missing something.

Could you click Support > Submit Diagnostics on your DVR web UI

The thought just occurred to me, does the thumb drive have to be formatted as device memory for the device to be able to delete files? I'd prefer to keep it as external memory so I could move it if I need or want to but maybe that's not going to work. Writing to it works great but deleting is the issue.

There is no "Trash" folder.
The recording is only marked for deletion. Default is to delete the recorded file the day after you delete it.
Like a Recycle bin, etc.

Ahhhhh...got it! I hadn't seen the display from your referenced thread about the trash. I found that display on my UI and sure enough, the shows I deleted today were marked to be deleted later. I'll watch them and ensure they definitely leave the thumb drive. I was thrown off track when the the file manager's I was testing wouldn't delete files either. I guess that's another quest. Thanks! You guys rock and I love what you're creating!
