Three attempts to burn one file of 4.4 GB and another of 5.5 GB in DL DVD-R (not on the same disk, of course), completes and verify OK in K3b but the files - including smaller ones (a few KB each) are unreadable. For example, a text file comes out like this:
I’ve burned DL disks before, but AFAIR not with >4GB files, so I believe this is a file size issue with the recording app, as recording files 4GB or less works flawlessly. This was tested with two different brand drives at the minimum record speed (4x), and both gave the same results.
Eventually, after making a nice set of coasters for my wife, I was able to record the 5.5 GB file successfully after changing from wodim from the standard repo to cdrecord from the multimidia:apps repo.
There’s a ugly discussion on the 2006 move from cdrecord to wodim due to licensing issues, but I won’t go into that.
Also, there’s a bug report of this somewhere (linked from a *ubuntu forum), but it’s old and there’s no workaround given.
I’m posting this in case it may help someone. YMMV.
Just a note: the corruption only appeared after the 4.4 GB barrier and if one of these files was 4.4GB or more. The files before (including the 4.4 GB file itself) can be read, the others, even the small ones, get corrupted.

And a very recent one in the factory list IIRC.

Have you tried growisofs for dual layer disks? Back in time I had problems with home video DVDs when burning DL disks. It took over a minute for the DVDs to load in my DVD player (but ok on Linux). I tried growisofs and they loaded within 10 seconds. If I recall, wodim did not split the layers evenly, but growisofs did. I know my problem was different than yours, but it’s worth a try. You may need to install a package to get this, I forget at the moments what it is.
Yes. At least with growisofs from the standard packman repo IINM, it wouldn’t even finish recording, just gave a write error halfway through the first layer, or something like that.

Maybe instead of wodim you could use the original cdrecord. It is
available from the multimedia:apps repository. Warning: the app needs to
be set suid.

FYI - I’ve had excellent results using xfburn for burning images K3b has troubles with.
Main issue I’ve run into in the past has’t been at 4gb but closer to the max capacity of the disk, approx 4.6gb.
Burning disks can be tricky sometimes, some images are designed for “over burning” - ie writing between tracks to squeeze a few more megabytes, sometimes can’t accommodate extra overhead which I suspect some apps like K3b might need.
Actually it never occurred to me to try making an ISO first and then burning it. It might have avoided the >4GB issue. I’ll keep the idea in mind if it happens again, thanks.

Of course I did, but I do not remember every detail a week after.
Didn’t you read my first post on this thread?

I had burning fail on Taiyo-Yuden DVD-R disc using k3b, so I use wodim for those. I’m not sure if it’s just DVD-R that this happens with, but up until I got these discs, growisofs worked fine with DVD+R. When I use DVD+R / DL discs (Verbatim, not the ones made in India), I have no trouble - but I usually only use DLs for backing up “movie” DVDs. Lately the Verbatim single layer DVD+R discs have been failing verify, that’s why I got the Taiyo-Yuden discs. It seems the Verbatims from India fail. Of course, I never had the particular problem you have been getting… so it might not be the discs you’re using, probably not…
Most of the times I started blaming the software, the media, openSUSE, the gods, myself, etc., a few times it was crappy/faked media, but mostly it was failing hardware. Changing the Drive usually fixed the problem, so frequently that I use two DVD recorders on my desktop now.
That’s what I did - I replaced the DVD burner, with a different brand name, still the same deal. Only the dual layer Verbatims work, single layer discs fail verify, Taiyo-Yuden single layer work fine. I would suspect “crappy/faked media” in this instance, but I’m sure it’ll be another reason in the future. I swear computers are haunted.
