On media that is not usable, I get the following error when I try to
use tar and read the file.
gzip: stdin: Input/output error
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
I attempted to run the same command above on the failed burn and I
received the following during the process.

The script is run by cron during the night. Reliability is more
important than performance. So I have set stream_recording off for
tonight on this media. I will see how it completes in the morning.
Thank you,
