Hoi Vegard,

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?
