I purchased LG GP57EB DVD
Burner which claims to be M-disc compatible.
I am wondering if there is some issue with ability to write to M-Disks;
when Blu-ray is not explicitly supported ?
Compare the specs for your LG GP57EB DVD Burner
with a LG BP50NB40
this is also a USB 2.0 interface but it explicitly states Blu-Ray support .
I mention this latter device now, because I was surprised there were
Linux driver issues with Blu-Ray;
so I bought one of these at MSY for $149; tried it on a laptop which
dual boots PureOs and Win7x64.
but PureOS couldn't see it. The Linux driver issues seem to concern
Blu-ray encryption and
don't seem like they are going to be fixed anytime soon......so I didn't
bother reporting the issue to the list !
If you are interested win7x64 is currently burning 18GB to a 25GB
Verbatim BD-R SL 6x M-Disk;
in the LG BP50NB40 drive via Burn-Aware; seems to be burning about
0.5GB/ min but this is over a LAN from this desktop
purchased 2 boxes Verbatim M-disc Bdr 25gb 5pk to use for trials. Both
mail-orders arrived recently.
I tried the new burner with ordinary DVD using brasero SW. It created
small data DVD without any issues. I created 21.2 GiB .iso with brasero also
without any issues.
When I asked brasero to burn it and presented one M-disc in the burner it
responded with "Please replace the disc with a supported CD or DVD". Search
results for “M-disc” in brasero help returned: 'No matching help pages found
in “Brasero Help”.
I also tried k3b with the same .iso. It asked for a disc, played a bit with
inserted M-disc and then stopped, still asking for "an empty Blu-Ray medium"
So far no success but also no coaster...
Any advice what to try next would be appreciated.
Sorry as mentioned above there seem to be encryption issues associated
with developing a Linux Blu-Ray driver;
although why this must prohibit writing one's own Bu-Ray or M-Disk I
have no idea !
