Re: WRITE@LBA=3e0c30h failed with SK=3h/WRITE ERROR]: Input/output error (DL)


> Question

It comes out of a wrapper script that converts
cdrecord options into runs of dvd+rw-tools.
The write command is supposed to be:
  growisofs \
    -use-the-force-luke \
    -use-the-force-luke=bufsize:16m \
    -use-the-force-luke=noload \
    -Z /dev/...=/dev/fd/0

Eventually there is also option

Hmm. That would also make questionable my
argumentation about Problem 2.

So if growisofs did not issue a layer break position
then Gregoire's drive may or may not have Problem 1.
But in Gregoire's scripts i do read -dvd-compat.
So probably the theory about number 2 still stands.

As for scdbackup:
I am quite sure that the failed growisofs run
for scdbackup was not with -dvd-compat or any other
option which causes a fixed size. The growisofs
wrapper works fine for sequential DVD-RW where
such a setting would cause the same error.

Obvious is the relation of error position, error
message and size of the plain ISO image.
Regrettably i cannot get that user to make more
experiments which each eat up one DL media.

The problem will have to wait for the next occasion
to show up.

Have a nice day :)
