M-Disc and GNU+Linux
M-Disc and GNU+Linux
Hello! I'm curious about whether special software is required for M-Disc engraving. Let me clarify. M-Disc uses a stone-like material instead of organic media, focusing on engraving rather than burning. These discs are designed to be extremely durable, potentially lasting over a thousand years. So, would you need specific tools for this process? I was thinking about using KDE's K3b app for burning, but after checking some Linux forums, most users rely on command-line tools. That’s fine, but it might not be the best option if you want reliability.
It seems like the main purpose here is likely Blu-Ray or M-Disc playback, especially since I found a source suggesting Blu-Ray M-Discs can handle high-resolution content like 4K at 60fps. The writer mentioned a sticker claiming 4K support, though it might just be branding. K3b does support Blu-Ray functionality.
From M-Disc's site, they mention hardware compatibility with Linux, which is interesting. For open-source options, you might want to look into software that adheres to GPL or MIT licenses. Let me know if you'd like more details!
@Grummy Old Man says K3b treats the DVD-R M-Disc like a regular DVD-R and works fine with it. He wonders about Blu-Ray M-Disc compatibility, noting they claim support too. He asks if K3b would keep engraving on top of a 50GB CD, filling unused space over time, and whether he’d be involved in that process. He’s curious about who controls these actions—whether the writer or the software decides.
The issue appears to be with appending files in K3b. The documentation mentions "Rewritable: no" and "Appendable: no" for the Medium version. I checked the provided link and found it supports UDF mode, but it doesn't address append functionality. Would you like me to explore alternative solutions?
@Grumpy Old Man Hmmm I failed.. I went to I am so fucking dumb, I basically threw away a gratis 25GB disc xD I didn't save my session.. Like I burned, it got some weird error (probably the "Verify written data"), but everything seemed to work on the disc.. then I re-inserted it and when I went to burn again it said that the disc didn't support multisessons.. But that was the disc that came with the thing, I haven't tried the EXPENSIVE discs yet xD.. learning, thankfully got some spare shitty ones to test my knowledge. What is your option on Project Properties > Misc > Multisession mode? by default it is on auto.. P.S. After I burned to the disc the 1st time - the variable "Appendable" changed from "no" to "yes" .. EDIT: It seems like after I burn - it will show the session items before the last one.. which is strange..... I probably need to close the multisession like you have instructed, but I do not know where to do that
I think the answer lies in removing the disc after each burn. Begin with multiple sessions, keep going as long as desired, and then conclude the process.
This discussion is a bit outdated, but I wanted to add another perspective. I've successfully created Mdiscs using K3b before, and I've also worked with BDXL, BDR, and DVD formats. For Blu Ray, LTH is likely the closest match. Regarding hardware, most devices function adequately even if the maker doesn't highlight Linux support. With Blu Ray, standard BDR users should work fine. For DVDs, opt for certified drives to ensure compatibility. I hope this gives a bit more clarity to the conversation. Mdiscs are really innovative!
