Title:
  Cannot Blank or burn to CDRW disk with SuperGrub2

Status in “cdrkit” package in Ubuntu:
  New

Bug description:
  Ubuntu 11.04, i386
  brasero 2.32.1-0ubuntu2

  My CDRW device:
  scsi 1:0:0:0: CD-ROM            HL-DT-ST DVD-RAM GH22NS30 2.00 PQ: 0 ANSI: 5

  I needed to fix my Linux box that cannot boot so I burned Supergrub2 to my pocket CDRW disk. No problem. I fixed my PC with Supergrub2 disk.
  http://download.berlios.de/supergrub/super_grub_disk_hybrid-1.98s1.iso

  I wanted to burn PartedMagic 6.6 to my pocket CDRW disk. I did this
  many times before but it was not working this time, I received message
  that there is no usable disk in my CDRW burner. I expected message
  that Disk has to be blanked before it can be used. It looked like my
  system is broken and cannot burn CDRW anymore.

  I blanked my CDRW disk with wodim and it fixed the problem:
  # wodim dev=/dev/scd0 blank=fast

  Once the disk was blanked, it works as expected. I guess that
  SuperGrub2 disk triggers some bug in Brasero. All blank/burn was done
  on the same PC (Ubuntu 11.04) with the same disk and drive.

  Steps to repeat the issue:
  1) download and burn SuperGrub2 ISO disk to your CDRW disk.
  http://download.berlios.de/supergrub/super_grub_disk_hybrid-1.98s1.iso
  2) try to burn (or blank) other ISO image to your CDRW disk with SuperGrub2 (use Braseiro or Gnome file manager)
