Sadly, this still affects me..
I have the LG USB DVD drive, model LGPC-ODD
dmesg reports it like this:
usb-storage: device found at 5
usb-storage: waiting for device to settle before scanning
usb-storage: device scan complete

If there are any Karmic users still subscribed to this bug, I could use
some help over at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/676351 . As far
as I can tell, it differs from this bug only by Ubuntu release. Karmic
is supposed to be supported for another 10 months.

Upgraded from lucid-proposed and it fixed the issue for me. Blanked

Now that a fix has been released for Lucid, please consider issuing a
release for those of us still using Karmic. This bug was first reported
over a year ago. That is the amount of time that I have been soldiering
on with a crippled system. I hope you can understand that, for a
beginner,
Accepted udev into lucid-proposed, the package will build now and be
available in a few hours. Please test and give feedback here. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed. Thank you in advance!

Martin, the code submitted to SRU PPA still contains the bug we
discussed in the turn of August / September, i.e. the distinction
between DWD-RW modes is put into feature_profiles instead of
cd_profiles, so the testers will be affected in the same way Arch users
were.
--
cdrom_id: Does not
Martin,
Yet another patch. If the disc is unreadable and reading of the first 32
blocks fails set the cd_media status to 0 (not present). This will
prevent udev from executing blkid next that tries to determine fs on the
disc and which in this case may seem to hang forever locking the drive.

Excuse me for my English, Martin. I'll tell you what I've done.
I use Ubuntu Lucid. I've updated udev, libudev0 and libgudev-1.0-0
packages from your ppa.
Then I've inserted DVD+RW with an information recorded on it.
Then I typed in terminal the command 'sudo /lib/udev/cdrom_id --debug
For people who are affected by this and are using 10.04: Can you please
add my sru-test PPA at
https://launchpad.net/~pitti/+archive/sru-test
and upgrade to the udev there? This should fix the issue. Can you please
give me the output of sudo /lib/udev/cdrom_id --debug /dev/sr0 again,
together
Martin,
It looks like Arch is using hald simultaneously with udev. I tested the
flawed build from Arch in Ubuntu on three different drives and see no
issues. Although 17 sectors is very unusual, it mostly works. Couldn't
be that a race condition with hald, that is deprecated in Ubuntu since
Caught red-handed! The issue occurs if the media is appendable (status
1): because of the improperly applied DVD-RW media variable (in features
instead of profiles) , everything is DVD-RW restricted overwrite just if
the device is DVD recorder and if the disk is appendable (CD-R, CD-RW or
DVD-RW
jonie,
there is a regression report at
http://bugs.archlinux.org/task/20550?string=udevproject=1type[0]=sev[0]=pri[0]=due[0]=reported[0]=cat[0]=status[0]=openpercent[0]=opened=dev=closed=duedatefrom=duedateto=changedfrom=changedto=openedfrom=openedto=closedfrom=closedto=
and
Martin,
the regressions snug in someway
- the patch to tell dwd-rw in sequential mode from restricted overwrite
mode posted in comment #63 is correct and is exactly the same as your
proposed fix, but I can take the blame for not having revised the
committed code thoroughly
- I don't know, where
Now it seems clear to me that if you request 17 blocks, many if not most
of firmwares will check only the MSB and make it 16 blocks, what means
that just sector 0 will be checked, which is non-empty solely in case of
rewritable DVD formatted to a filesystem such as fat32/ext2, all ISO and
UDF

I think there's nothing to worry, just to be exact the commit

you changed it)

Eventually we should backport this to lucid, but let's give it some time
to bake in Maverick first (see bug 620977).

Yet another fix:
no next session for appendable DVD-RW 13h, this fixes the aforementioned iso
burning bug:
- if ((header[2] 3) 2)
+ if ((header[2] 3) 2 !cd_media_dvd_rw_ro)
cd_media_session_next = header[10] 8 | header[5];
--
cdrom_id: Does not recognize
Just to be sure, by aforementioned burning bug, do you mean the second
paragraph in comment 62, right? That was supposed to be fixed in
http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=cf2205a1986222fdc0238190f5742f54d943cd23
, so that it reports the correct state blank.
So brasero
You're right. I meant comment #62 - the disc was recognized and it was
possible to burn a data compilation, but Brasero choked when burning an
iso image. I thought initially that it is a problem with Brasero, but
after patching ID_CDROM_MEDIA_SESSION_NEXT it works well in both modes.
The fix you
There are two elements that need to be put together as I figured it out:
- are there any usable data we want to preserve, if not set the status to blank
- can we append a session - for rewritable DVD we can't with two exceptions: a
virgin DVD+RW (that is reported blank by the drive) and DVD-RW
Thanks jonie, pushed upstream in commit
