I have the exact same problem as Thomas, above. A few minutes after booting, the CD/DVD drive disappears, never to return, with the exact same type of errors:

Aftwards, drive utility still shows it as being there, but refuses to acknowledge that there's media in the drive (see screenshot) wodim --devices returns nothing lshw -short doesn't show the CD/DVD burner. Mine is also a TSSCorp drive. This started happening after upgrading to 10.04 LTS, no problems on prior 9.0x versions. I am still relatively new to Ubuntu/linux, and will gladly run any traces/reports if told what to run. Unfortunately I am not in a position to upgrade to the development release. Thanks. ** Attachment added: "Disk Utility screenshot" http://launchpadlibrarian.net/51298280/Screenshot1.png -- dvd / cd drives not handled correctly in 10.04 LTS https://bugs.launchpad.net/bugs/577465 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
