when i try to blank a cdrw, i get an error 255 but when i copy and paste the the string from k3b to rease the cd, cdrecord on the konsole does the job.

k3b used the following to blank the cd:
/usr/bin/cdrecord -v dev=0,0,0 speed=8 -eject blank=fast

here is the konsole output when i try to erase a CDRW with k3b:
