Comment 38 for bug 561585

Please clarify if this is the way it should work in Lucid.

After waiting for a patched udev release I'm currently running udev 151-12 on Lucid amd64 beta2 up to date.

from my fstab, (same as Karmic): /dev/sr0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

Two devices connected to the IDE port:

    dvd r/w: /dev/sr1
    legacy zipdrive: /media/ntfs-1 (not listed in fstab)

When media is inserted at zipdrive no auto mounting occurs although media can be seen at Places/Computer and root mounted from there.

from syslog:

When a written CD is inserted, its icon becomes available at "Places". Different from Karmic, the icon has to be clicked to mount it.

When a blank CD is inserted, the same happens, the icon becomes available but as empty CD, it cannot be mounted, although (it seems) it can be accessed by a CD burning application.

If I try to mount a blank CD the following error is displayed:

Unable to mount cdrom0

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so
