I had an old reliable desktop running WinXP, but after some registry errors caused the system to be unstable I thought I'd give Ubuntu a try. I booted the 12.04 iso from the CD drive and the installation seemed to go smoothly. However, after installing updates and re-booting neither of my optical drives seem to work. One is a TDK CDRW 24/10/40B and the other a Pioneer DVR-105.

output from sudo lshw | grep cdrom:

   *-cdrom:0 logical name: /dev/cdrom1
*-cdrom:1 logical name: /dev/cdrom

output from sudo lshw

Looking through other posts that dealt with the same problem, I installed libdvdnav4, libdvdcss2, libdvdcss-dev, libdvdread4, gstreamer0.10-plugins-bad and gstreamer0.10-plugins-ugly packages. I can see both drives from the Computer window, but neither shows under Devices on the left side of file manager.

I'd appreciate some help if anyone has any suggestions. Thanks!

to find out if the recorder was recognized, type dmesg | grep "sr0" in a terminal. You should get a response similar to:

[    1.649270] sr0: scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2 cdda tray
[    1.649445] sr 0:0:0:0: Attached scsi CD-ROM sr0

check mounted non-blank media: To be sure there it is not mounted execute this in a terminal: mount | grep "/dev/sr" If the response is blank there is no non-blank media mounted in your media drive. Blank media is not showing up here.

Note: your drive might be called sr1 or sr2 if you have several; in that case replace sr0 with sr1 in that case (or simply sr to catch them all).

Sorry, forgot to add that nothing happens from mount | grep "/dev/sr" with blank or non-blank media – jase Aug 9 '13 at 10:14
