Description of problem:
Right clicking a DVD icon and selecting 'Eject' on GNOME desktop gives an error and the medium is
not ejected. (It _is_ unmounted).
More details :
[stein@localhost ~]$ eject /dev/scd0 -v
eject: device name is `/dev/scd0'
eject: expanded name is `/dev/scd0'
eject: `/dev/scd0' is not mounted
eject: `/dev/scd0' is not a mount point
eject: `/dev/scd0' is not a multipartition device
eject: unable to open `/dev/scd0'
[stein@localhost ~]$ ls -l /dev/scd0
brw-r----- 1 root disk 11, 0 May 31 19:51 /dev/scd0
[stein@localhost ~]$ ls -l /dev/hda
brw------- 1 stein disk 3, 0 May 31 2005 /dev/hda
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I tried to connect the unit via USB and FireWire. It behaves the same in both cases.
$ ls -l /dev/cd*
~]$ ls -l /dev/cd*
lrwxrwxrwx 1 root root 3 Jun 8 2005 /dev/cdrom -> hda
lrwxrwxrwx 1 root root 3 Jun 8 2005 /dev/cdrom1 -> hdb
lrwxrwxrwx 1 root root 3 Jun 8 2005 /dev/cdrom2 -> hdc
lrwxrwxrwx 1 root root 4 Jun 7 23:22 /dev/cdrom3 -> scd0
lrwxrwxrwx 1 root root 3 Jun 8 2005 /dev/cdwriter -> hda
lrwxrwxrwx 1 root root 4 Jun 7 23:22 /dev/cdwriter1 -> scd0
I also discovered, that the problem happens only, if I plug in the drive after I
logged in :
- plugin the drive _before_ boot : ls -l /dev/scd0
brw------- 1 stein disk 11, 0 Jun 7 23:22 /dev/scd0
- plugin the drive after boot, before login : ls -l /dev/scd0
brw------- 1 stein disk 11, 0 Jun 7 23:35 /dev/scd0
- plugin the drive after logging in : ls -l /dev/scd0
brw-r----- 1 root disk 11, 0 Jun 7 23:39 /dev/scd0
First user who logs in gets all the devices... so you may have to login as an
ordinary user first?
