<p>Hi Will!<br>
</p>
<blockquote type="cite">
<pre><blockquote type="cite" style="color:rgb(0,124,255)"><pre>It sounds like a disk drive error if the file copy fails at that point.
If the file copy fails there is not much chance that MythTV could read
past that point. I recommend replacing the drive. Copy as much as you
can from the old drive to the new drive.
</pre></blockquote><pre>Easy to check by installing smartmontools and running:
sudo smartctl -a <i>dev</i><device> (e.g. /dev/sda)
It might be obvious that it's dying, or if not, I'm sure somebody here
could provide some insight if you paste the input here.

</p>
<p>I'm guessing with all the 'old-age' and 'pre-fails' in the output
and the drive is around ten years old Peter's suggestion to
replace it is probably a good one. ...When putting together this
new Backend I sort of grabbed the first about-the-right-size drive
I saw in the box and didn't even look at the date - oops!</p>
<p><br>
</p>
<p>Anyway, below are the test results. I'm thinking your comments
would be a great way for me and the rest of the readers to learn.
I'm also thinking it might be a good idea for me to create a
script to look at the smartctl results to monitor the hard drives
in the various computers around here and so catch any problems
early. So the sub-question is which items should I be monitoring?<br>

<p>The replacement drive has been ordered: for $10 more I got a 6 TB
over 4 TB WD6004FZBX: 256 MB cache (seems more is better), 7200
RPM, (seems less of a bottleneck possibility that the 5400 RPM
versions), 5 year warranty (seems if the manufacturer stands
behind their product for a longer time), Transfer Rate up to 267
Mbps (faster is better, though is it reading or writing....).
SSDs and NVMe's are faster but I'm not a fan of when they fail
they take everything. OTOH I do back up my hard drives.......</p>
