Comment 28 for bug 220957

So hal sees the drive and the capabilities, but does not detect the (empty) volume. Unfortunately I cannot tell much more from the currently existing information here.

If you insert a blank CD-ROM, wait a bit, and do "dmesg | tail" in a terminal, can you please copy&paste the output here? The only line that should appear after inserting a blank DVD is

  [12993.587466] cdrom: This disc doesn't have any tracks I recognize!

(different timestamp at the front, of course).

Also, it would be helpful to watch what hal is detecting. Can you please do the procedure on https://wiki.ubuntu.com/DebuggingHal and attach the log? Then we can compare it with the output on a system where it works (e. g. mine), see below.

For the record, I also have an ATAPI burner, and Hardy uses the SCSI emulation.
