Comment 9 for bug 581925

Hello. Sorry I haven't been able to follow on this before. Thanks for looking at this, Martin.

Right now, my optical drive is not working. Blank CDs and DVDs are not recognized, I've tried using Gnomebaker but it didn't "see" the disks either. Also, I've tried inserting data DVDs and an audio CD, and they were not mounted either. The green LED lights up for a bit, but then I can hear the drive stops spinning and the disks are not mounted.

Of course I've wondered if it's a hardware failure, so I've rebooted into Windows XP (dual boot machine). When running Windows XP, the drive works correctly, I can read data DVDs, audio CDs and burn DVDs with InfraRecorder. I made the tests in Windows with the same disks I was trying to mount under Ubuntu, so I know it's not a problem with the disks themselves.

Until a few weeks ago the drive was working correctly with Karmic, both for reading and burning.

In my original bug report I said I could mount data DVDs. Now I think I was mistaken, I had a memory of mounting DVDs but actually I last did it with Karmic. I'm 90% sure I haven't been able to mount data DVDs since installing Lucid. I'm 100% sure blank CDs and DVDs haven't ever been recognized by this machine since installing Lucid. I'm really sorry for the confusion.

Anyway, here's the output to the commands you asked.

amatriain@amatriain-desktop:~$ ps aux|grep udisks.*poll

I also tried inserting a blank DVD and running udevadm, as you suggested to Tastyracer. This is the output:

amatriain@amatriain-desktop:~$ sudo udevadm trigger --verbose --sysname-match=sr0
/sys/devices/pci0000:00/0000:00:0f.1/host3/target3:0:0/3:0:0:0/block/sr0

After running udevadm the blank DVD still did not appear in nautilus or the Desktop, and Brasero wasn't aware a blank DVD had been inserted.

Anything else I can do to give you clues to what's happening?
