Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jonathan Underwood 2012-01-23 16:28:27 UTC
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).

# 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.
  
Actual results:
Blank CD-R not seen by Brasero

DVD-ROM? Is it a writer?

Comment 4 Jonathan Underwood 2012-01-25 16:14:33 UTC
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.
