Interesting reading there, with many of the messages recognised from my 
experiments (see Users list, thread 'Are RWs a problem?').  The difference, 
though, is that on my system k3b appears to have done the erase, but mkisofs 
fails.  You are left with a disk that cannot be mounted.  At one point I got 
lots of 'bad sector' warnings, and every time I got 'I/O error' reports.  
Following a lead I got from a LUG member, I found that cdrecord, from a 
terminal, could not do a blank and record in one command, but if the command 
is split they work fine.  I successfully burned to a disk that had seemed to 
be unusable, from reading k3b's output.  Full details can be found on the 
user list thread, if they help.
