Description of problem: My machine no longer sees new blank CD-Rs inserted into the drive. I have verified the CD-Rs I am using are fine (they work recognized on other machines) and other operating systems on the same machine (so the drive is not defective). Version-Release number of selected component (if applicable): # rpm -qa | grep udev libgudev1-147-2.35.el6.x86_64 python-gudev-147.1-4.el6_0.1.x86_64 libudev-147-2.35.el6.x86_64 udev-147-2.35.el6.x86_64 system-config-printer-udev-1.1.16-17.el6_1.2.x86_64 How reproducible: Everytime Steps to Reproduce: 1. Insert blank CD-R 2. Blank CD-R not see by eg. brasero 3.

cd_inquiry: INQUIRY: [PLDS ][DVD-ROM DH-16D5S][VD15] DVD-ROM? Is it a writer?
Well, that's embarrassing. I ordered 5 machines with he same spec, all supposed to have writers. Four do, this one has been misconfigured and has only a reader. What an idiot. Sorry for the noise.
