Recording and remote viewing issues

Channels Apple TV Troubleshooting
#1

Don’t know if this is related to the latest Shield firmware update or not but recently seems like recordings are failing and remote viewing via the web or the iphone app fails. When the remote viewing fails I keep seeing that the HDHRun Prime buffer is full, see snippet from DVR log below.

The only things I have done in the past week are to update the Shield firmware and update the DVR app running on the Shield via the Google Play store. I have made no other changes to my network setup, AppleTV, etc.

The error messages sound like your DVR drive is not attached, running out of space or that it’s name changed.

#3

I will check the connection when I get home but that would surprise me as the Shield and the USB drive are in a cabinet and have not been moved for weeks.

The drive is defiantly not out of space, showing 2.5 GB available.

How would the drive name get changed and how would I know?

Try playing existing recordings to see if they work.

Also try use a file explorer app, or go to x.x.x.x:8089/restore to navigate around the filesystem to see if the /storage/3A70D09670D059E9 is still valid.

#5

Existing recordings won’t play, went to x.x.x.x:8089/restore and /storage/3A70D09670D059E9 appears to still be valid, meaning I can see folders and navigate to them although response seems to be slow.

I tried copying a recording made this morning from the USB drive to my Mac via wifi to see if I could play the file from my computer once it copied over and got this error: The operation can’t be completed because an unexpected error occurred (error code -8084).

What next?

And here’s the error log from this evening when I got home and tried to play recordings via the web interface on my computer:

Maybe a disk failure? You could try shutting things down for a bit and then booting back up to see if that helps.
