I recently upgraded my laptop from fedora 6 to fedora 7. Now I've discovered I can no longer burn CDs or DVDs. I have an old CD-R burner, so this is not critical yet, but I will need to get this figured out. The drive is identified below in the wodim output, but is a fairly typical IDE combo drive. As I recall, it was /dev/hdb with fedora 6. Now with fedora 7 the drives get scsi style names.
Besides the output from wodim (a typical run is pasted below) there are also syslog messages like: Sep 11 00:09:35 laptop kernel: cdrom: This disc doesn't have any tracks I recognize! which seems like a media problem, but happens for all of the media that I've tried. My assumption is that the laptop cut some corner with the drive setup so that there are errors which got ignored or went undetected in fedora 6. Booting the fedora live CD into RAM made no difference so it should not be some peculiarity of my software configuration. Booting from Knoppix ties up the drive so that I can't burn. I'll be trying to boot from USB with an alternative distro (Knoppix? PuppyOS?) to prove the hardware works, but thought it would be worth soliciting advice. (Google has not helped as entirely too many people have burn problems.) (I ran this as root just in case that mattered) wodim dev=/dev/scd0 driveropts=burnfree,noforcespeed -dao -immed OpenCD-07.09.iso Error trying to open /dev/scd0 exclusively (Device or resource busy)... retrying in 1 second.
