I admit I have never heard about or used

I ran setcap as you suggested in your

<br>
Five years ago I burned several labeled
"LongLife" Verbatim BD-R DL/50 Gb discs
with the same LG burner and previous
K3b/Cdrecord. When these discs became EOL,
I tried corresponding 'Mediarange' discs.
These failed to burn and Cdrecord
returned an unknown error (code 254). This
error 254 is posted on some forums with
different solutions. <br>
Some said burning could be broken by some
unfrienly programs. Regarding Mediarange,
Joerg Schilling suggested to upgrade the
burner's firmware, but still no burning
success with those Mediarange discs
anymore.<br>

Yes, I have tested xorriso and contaced Thomas Schmitt,
both with my old LG burner and a new ASUS burner. It
turns out that the old burner has lost its capability to
write newer BD-R DL discs. Yet it still manages BD-RE DL
discs. The quite new ASUS burner manages my previous
problematic MediaRange BD-R DL discs.<br>
It is claimed to have M-disc support ("1000-year storage
solution").<br>
<br>
According to wikipedia M-DISC (Millennial Disc) is a
write-once optical disc technology introduced in 2009 by
Millenniata, Inc. and available as DVD and Blu-ray
discs. <br>
<br>
Regarding prices I have verified that Verbatim Lifetime
Archival M-Disc are priced about 3x normal disc quality
like Verbatim DataLifePlus BD-R DL, and > 3x prices
of some lower cost discs like MediaRange and Primeon. I
am not (yet) convinced M-discs are worth the high prices
for normal or personal arhival. IMO I have not yet seen
proved experience regarding longevity for normal quality
BD-R/RE discs. Some say as low as 5-7 years, other 10-20
or even 20-50 years.<br>

I have currently had some more success to
complete burn some unbranded BD-RE/DL
discs from Slowmoose, with less failing.
The remarkable is that the disc burn is so
unstable and inconsistently, as it may
fail on the first two attemps before it
succeed on the third. Some burns may fail
immediately, other not so fun after 1 or
1.5 hour(s), or ca. 1/3-1/2 of total
burning time for 40 Gb)<br>
<br>
I maybe read somewhere that som other
burning programs could "leave disc without
"closing session" (or similar?), and
Cdrecord next could run into issue to
rewrite those discs afterwards. I know I
have tried also 'dd' on some discs.<br>

Many articles recommend to keep
three types of media for
archiving stored on at least two
locations to spread the risk.<br>
For camcorded video this
envolves for me <br>
<ol>
<li>keep the source media
(tape cassettes)</li>
<li>a digitized version on
portable expansion USB3
discs</li>
<li>and on optical Blu-ray
data discs and playable
BD-video discs. </li>
</ol>
