hal can't mount a dvd on a usb dvd recorder

[humufr]

I have an usb dvd recorder. I can burn dvd with it without problem but ubuntu dapper can't mount automaticlly the dvd after it. If I'm using the command "pmount /dev/scd0", the dvd is mounted correctly.

The last lines in dmesg are (the last four lines are print after pmount command):

You mean that a burned CD is not immediately mounted after burning it? Does it work if you eject the CD and reinsert it again?

Breezy did not have this problem since CDs were automatically ejected after burning by default, since many burners do not correctly re-init a burned CD. However, Dapper's n-cd-burner now does not do this at all any more; apart from being annoying by itself (I never notice when a CD has finished burning), it also causes this behaviour.

no I mean that if I'm trying to insert the dvd burned 2 days latter, ubuntu can't mount automatically but it's working fine with pmount. I must add that the problem seems to appeared only with dvd-r, this we I burned a dvd+r and this problem didn't showed up.

[Martin Pitt (pitti)]

Ah, I see. Please do the debugging steps at http://wiki.ubuntu.com/DebuggingRemovableDevices then. Thank you!

So hal sees the CD-ROM drive, but doesn't seem to notice that there's a CD in it.

Can you please copy&paste the output of

  for i in `ps aux|grep hald-addon-storage | grep -v grep | awk '{ print $2}'`; do sudo grep -z HAL_PROP_BLOCK_DEVICE /proc/$i/environ; done | tr '\000' '\n'

here? Also, does it work if you start the computer with the CD already inserted?

Thanks, so it seems that the storage addon is at least polling the drives. Apparently it fails to notice the DVD.

Does it work with a normal CD-ROM?
Also, does it work if you start the computer with the DVD already inserted?

[Martin Pitt (pitti)]

This smells like bug 56484. Can you please test this with the latest Edgy packages and check whether you still have the problem?

[humufr (humufr-deactivatedaccount)]

sorry I can't, I'm using my computer for work and so I prefere to stay with dapper at least for the next months. I'll try to install edgy on a usb disk when I'll have time but don't know exactly when. Sorry

[Sebastien Bacher (seb128)]

Nicolas, maybe you can try the patch from the edgy package on dapper if you know how to build a patched package

Martin, does the patch apply to dapper, should it be backported?

[Martin Pitt (pitti)]

Seb, yes, the patch should be fine for dapper. I just added a dapper task to bug 56484 and requested mdz's blessing.
