Some thing wrong with k3b

[S. M. Ibrahim]

I am trying to burn a Cd using k3b and got this error.

Sense flags: Blk 0 (not valid) 
cmd finished after 0.835s timeout 480s
cmd finished after 0.835s timeout 480s
Fixating time:    0.839s
/usr/bin/cdrecord: Cannot fixate disk.
/usr/bin/cdrecord: fifo had 241 puts and 178 gets.
/usr/bin/cdrecord: fifo was 0 times empty and 166 times full, min fill was 93%.
BURN-Free was never needed.

cdrecord comand:
-----------------------
/usr/bin/cdrecord -v gracetime=2 dev=/dev/ide/host0/bus1/target1/lun0/cd speed=12 -dao driveropts=burnfree -eject -data /tmp/kde-lavlu/k3b_0.iso

Here i just use copy cd.
