ubuntu doesn't recognize my blank cd.

[Markus Bertheau]

I downloaded an ISO file and wanted to burn it. Ubuntu tells me to insert a
blank CD in the drive, but there already is a blank CD in the drive. It doesn't
let me burn.

Does it do that with every blank CD you put in the drive, or just a particular type?

Is it a new thing due to a recent update, or you have never been able to burn
before?

Are you using Warty or Hoary?

Well, I just have this type of CDs around. I have ubuntu installed for just a
week now; I didn't try other blank CD types.

I remember to have tried several days ago; it failed with the same error message.

Hmm, the latest development preview thingie. I always update everything when
that icon appears in the top panel.

I'm noticing the same on FC rawhide. The device manager says, the size of the
blank cd volume is 2048. I think that number should be more like 700*1024*1024,
and if it was, nautilus-cd-burner wouldn't complain.

can you look in the device manager what is the value of "volume.disc.is_blank"
for this volume ?

It says 1.

Thanks for the screenshots and comment, I've opened a bug upstream with all
that: http://bugzilla.gnome.org/show_bug.cgi?id=172429 and I'll let you know
when they give some feedback.

upstream is asking if you can attach the output of lshal with and without the
blank CD

Markus, do you still have this problem in Breezy? If so, can you please attach
the "lshal" output with the current hal again?

[Nelson Benitez (gnel)]

Hi,
I have this bug on gentoo and I have put a comment[1] where I came to a
conclusion this is a file permission error on the device file. Maybe someone can
test if that is what is happening on ubuntu.

But that actually looks fine. What is not working for you?

Markus, I still need the lshal output from you, and also the output of 'ls -l
/dev/hd* /dev/cdrom' (to check device permissions).

[Martin Pitt (pitti)]

No answer for a month, so I close this bug for now to clean up Bugzilla. I will
reopen the bug if I get an answer.
