K3b problems

K3b thinks there is a blank CD disc in the drive when there is not. At first, I thought it was the drive, and I went and bought a new one. I still have the same problem - except now I can actually write to the disk sometimes. Both CD and DVD projects are being written. However, on the CD audio project, it said the medium was too small for the project after selecting one 4:48 minute song. It actually burned the Slackware-current iso which seems to be fine. I got Brasero from sbo to burn the CD audio project.

I still think my old ASUS writer was bad for DVD burning since it went through the motions but only the title was burned to the disk, no data. Brasero works fine, but I wish I knew what happened to K3b.
