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

      *-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.
