Hi,

LBA=10h means that the second WRITE command yielded a failure message
from the drive. The accusation is strange.

I have seen this only with cdrecord yet, when the Linux kernel reported
(falsely) to cdrecord that the bytes of the previous WRITE command had
not been transmitted. cdrecord then repeated the WRITE command and got
above error reply.

Looking at the code of function poor_mans_pwrite64() in growisofs_mmc.cpp
  https://sources.debian.net/src/dvd%2Brw-tools/7.1-11/growisofs_mmc.cpp/#L466
it seems that growisofs repeats WRITE commands only when the drive invites
this by one of two "NOT READY" replies: "LONG WRITE IN PROGRESS" and
"IN PROCESS OF BECOMING READY".

Whatever, this behavior is not normal.

RMA means "Recording Management Area". This is on DVD-R what Table-of-Content
is on CD-R. It records the structure of sessions and tracks.

growisofs says "updating RMA" before it issues the CLOSE TRACK/SESSION
command at the end of a DVD-R run with write type "Incremental".

If you can talk K3B into using write type "DAO" (aka "Disc-at-Once"),
then this might be worth a try.
Given the endurance with failure, i have few hope for success, though.

Afaik, the lasers for CD and DVD are different devices inside the burner.
(I recently had the case that a Blu-ray burner lost its sight for BD media
but not for DVD or CD.)


Have a nice day :)
