After doing all the configurations listed below this burner has worked
If I should write a checklist on what I needed to fix, it would be:
- SCSI emulation (couldn't burn a working cd without this!!!)
- Set CDRECORD to SUID (dpkg-reconfigure cdrecord)
- listen to all errormessages you may see when starting k3b, and
- Edit /etc/cdrecord/cdrecord so it includes correct driver
If you don't have this info, you can find burnerspecs
on the web, use google.
Sometimes it helps to set MAX_BURNERSPEED to less than
the one given by
the burner-specs. In my case I adjusted it down from
48x to 40x...
- Set rights to all devices needed for the cd-burner (these can be
more than just one...)
with scsi emulation on my computer this was /dev/scd1 ,
/dev/sg1 , /dev/cdrw (just a symlink),
and make sure the devices is owned by a group you are a
Good luck!! If you need detailed explenations on this, say so and I
will hand it to you when
I am at home by the PC.
Thanks for your detailed explanation! I can skip the k3b part because I
mainly use the plain cdrecord command, and sometimes xcdroast, also a
graphical frontend to cdrecord.
I've indeed gone through all the steps you mentioned and ran cdrecord as
root! I even reduced the writing speed to 2! Running cdrecord with the
-v option shows no errors at all. Using both the -v and -V option
results in more output, which shows some scsi errors after fixating, and
just before ejecting the disk! However I don't understand those messages!
I can't show you an example right now, because I removed the writer from
the Linux box, and have it checked for possible hardware problems.
By the way, is the Lite-On LTR-48126S a recent model that is still
available on the market?
