I'm sorry I don't know if CDs do that too, I use/have only DVDs since they are cheaper and faster. I've seen the bug again some day ago by just putting a DVD in the drive, whatching the contents in nautilus, and wanting to eject it. It's not an easily reproducable bug, or I just don't see what realy causes it yet.
If you have any idea, let me know and I'll try that. -- DVD can't be ejected sometimes https://launchpad.net/bugs/56216 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
