#archiving data on BD-R XL #MDisc
Bought the more expensive discs to ensure to preseverve the data for at least the next century. Here is a picture of the media before and after burning it. Of course the disc can‘t be read anymore.

@felsqualle @fuchsiii that's because around 2010s they cheaped out with organic binder (same shit as #LaserDisc used) and decided that's good enough.

• Consider imaging your stuff and/or using #MDISC recordables...

#DiscRot

@felsqualle @fuchsiii yeah, you guys can thank the folks who thought it was a great idea to use the same organic binder as used in the #LaserDisc...

• If you need optical archives, consider buying #MDISC recordables...

@raccoon what kind of discs?

#BDXL-#MDISC|s?

I mean I'd love to be able to afford an #LTO9 - #TapeDrive...

Another one for the #archive #datahoarder #storage #nas bubble:

What is the ~best DVD-ROM drive to read old and likely degraded media?

The Internet at large seems devoid of any information, it's all AI and linkfarming slop.

Are #MDisc worth it? If yes, what drive, disk manufacturer etc do I want? Are 100GB discs are reliable as 50 and 25 ones?
#HDD have shorter life? #LTO #tape seems less portable?

Retoots and replies *very* much appreciated.

🧵 6/n next time, i won't be double-compressing my #MDISC #BDXL #backup.

I can't use the disc image directly, because in my infinite wisdom, i've compressed the already compressed file system.

Now i get to wait another hour-ish, before i can access my rather old files.

Well, i can try and scrape 'em off the busted NVMe.

I just learned about bluray m-discs, and now I want to use them for long-term backups. I realise I have no followers, but does anyone have any advice for (Windows) software to write the discs? #MDisc #backup #bluray

Lo mejor de todo es que es un #CD-R. La capa física en la que se graban los «pits» y «lands» (hoyos y mesetas) es un polímero (https://en.wikipedia.org/wiki/CD-R#dyes) a diferencia de los #BD-R #HTL que es un metal (https://en.wikipedia.org/wiki/Blu-ray_Disc_recordable#HTL_(high_to_low)). Es decir, que la durabilidad del CD-R es menor.

La superfície de grabación de los #MDISC, sean DVD-R o BD-R es mineral. Aún más duradera.

@mos_8502 4/10

Only 120mm doscs, not 80mm discs tho.

I want to see 80mm BD-RWs and 80mm #MDISC|s as well as #credit itCard-CD's and #Businesscard-DVD's...

Wired idea; floppy discs, but M-Disc.

I this a thing, or is it just a weird idea? #floppy #MDisc

#TIL about M-Disc

#MDisc

@Akiko @CliffWade np.

I just wanr to avoid using ODDs and burning.new since - like with 3,5" FDDs - Quality of #Recordables has gone down the drain and there are no #MDISC-#ReWriteables...

Furthermore #DVDRAM doesn't work reliably as bottable media, if at all.

@itzzenxx @eve why not?

I wounder if there are #MDISC #HDDVD-#Rewritables...

Did I ever think I would find myself using optical discs again? Certainly not!

As it turns out, the Blu Ray format (+ M-DISC) are rated to last quite a while! I’ve been in the process of copying my oldest VOD’s onto disc for long-term preservation.

Do you guys do the same?

Ich glaub ich sollte bald ne modernere #ConcomVase baun...

Gibt's eigentlich #MDISC - #CDR's?

The Disc Duplicator M-Disc upgrade went well! Everything seems to work on a hardware level.

Next, I have to start installing and testing software:

I have a low-level USB library in Python that I got from AdaFruit that I'll be using to test the robotics codes I have in my notes.

I will have to find the instructions on installing the Lexmark Z600 driver that is supposed to work with this printer (and also understand how it works for disk printing).

And I suppose I will need some kind of python library for accessing the M-Disc burner, reading and writing media, and controlling the open/close of the disk tray from software.

Then I'll have to write the code to do the top-level control of those.

I'll first set these up to run from the command line (or the Python interactive interpreter). Ultimately, I want to be able to control it from a browser, so I can attach the duplicator to a different computer if I want to.

So after I get the low-level stuff working, I plan to create a little Flask web application. And it's a disc burner. Hence, my working project title, "Bunsen".

So, there's still many steps left. #FilmFreedom #Infrastructure #DiscDuplicator #M-Disc

These parts arrived in the mail today, so I now have what I need for the M-Disc disc duplicator project. Planning to get started on that tomorrow!
#Infrastructure #Hardware #DiscDuplicator #M-Disc

Have published the first two installments documenting my process on this. I've got the M-Disc writer for the upgrade ordered now. When it gets here, I'll write up the installation, and then it's on to the software testing.
