From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.4) Gecko/20030614 Description of problem: It's not easy and intuitive to reburn a data CD on CD-RW medium. An intuitive way is simply to insert the CD, put new content into burn:// and after pressing "burn" button choose to "Clear CD". Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Create a test data CD-RW disc. Ensure that it is CD-RW and that is a data disc (ISO). 2. Insert the medium into the burning device (It will be automounted as data CD now). 3. Nop (skip this step to reproduce the bug, see additional info) 4. Open the burner, add files and choose "burn CD" 5. In the dialog that appears choose "Clear CD" and so on. Press OK button Actual Results: Error message appears saying that the device "/dev/<device>" couldn't be opened in exclusive access mode. Expected Results: The CD should be unmounted and burned. Additional info: If you replace the step 3 with "open a root shell and enter "umount /dev/cdrom" command", everything goes fine.
This is so obvious that I cannot believe this bug survived until now. A simple umount /mnt/cdrom cdrdao blank Does the trick in command line.
nautilus-cd-burner 2.8.3-4 should fix this.
-5 has a "better" fix. -4 sometimes showed the dialog even though the unmount succeeded.
