Subject: [Hampshire] Strange handling of multiple optical drives in Mint 17
I recently installed Linux Mint 17 (Cinnamon) on my desktop and laptop
machines, as a successor to 13, the previous LTS release. The laptop is
behaving OK, but I have a peculiarity on the desktop, which has two
optical drives, both Optiarc AD-7173A DVD writers, as master and slave
on the IDE interface (all the HDD are SATA).

In Mint *13*, "Computer" showed the two optical drives as one would
expect; loading a CD or DVD into either drive showed up the type of
disc, and an audio CD started up sound-juicer so I could rip the CD (one
of my regular jobs is to take the CD recording of the Sunday morning
service at our church, rip it, extract the sermon and put the MP3 file
of the sermon on the church web site). Brasero could also see a blank
recordable CD and prompt me what to do with it.

In Mint *17*, "Computer" showed only one optical drive rather than two;
loading an audio CD into the *master* drive shows up the audio disc in
"Computer" and (I've configured the system to do so) starts
sound-juicer. However sound-juicer looks for the track listing on the
*slave* drive. Loading an audio CD into the *slave* drive doesn't
trigger sound-juicer or show up in "Computer", but if I start
sound-juicer, I get the track listing for the CD in the slave drive. If
I right-click on the optical drive icon and select Eject, it ejects the
*slave* drive. There is a similar effect with brasero, the optical disc
burning tool: a blank recordable CD or DVD in the *master* drive wakes
up brasero, but once it's awake it wants to deal with the disc (if any)
in the *slave* drive.

lshw -c disk shows the data for the two optical drives:

   *-cdrom:0
        description: DVD-RAM writer
        product: DVD RW AD-7173A
        vendor: Optiarc
        physical id: 0.0.0
        bus info: scsi@0:0.0.0
        logical name: /dev/cdrom
        logical name: /dev/sr0
        version: 1-01
        serial: [
        capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
        configuration: ansiversion=5 status=ready
      *-medium
           physical id: 0
           logical name: /dev/cdrom
   *-cdrom:1
        description: DVD-RAM writer
        product: DVD RW AD-7173A
        vendor: Optiarc
        physical id: 0.1.0
        bus info: scsi@0:0.1.0
        logical name: /dev/sr1
        version: 1-01
        serial: [
        capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
        configuration: ansiversion=5 status=ready
      *-medium
           physical id: 0
           logical name: /dev/sr1


which looks plausible to me, and suggests that the problem is at a
higher layer.

Can anyone suggest where to start digging, please? I've tried posting on
the Linux Mint forums but met with a resounding silence...

Thanks in advance for any help.
