Hi all,
I appear to have a problem with my DVD reader (Gigabyte Technology 16x16 DVD rw/r).
Check if you have a newer firmware for it (manufacturer or reseller site).
When I put a dvd in the tray, sometimes the DVD title comes up in the "recent device" window, sometimes nothing. When "nothing" comes up, sometimes the tray is locked& I can't get the disc out again.
For every action you take that ends with a faulty/unusual behavior, check: # tail /var/log/messages

Thanks JB,
a) yes there is a newer firmware (came out in 2005, rather than the 2002 version I'm running!) B U T..... it's a Windoze .exe file & how does one get it to a device in F14 (no floppy, Win XP running on a Virtual Machine? My searches of the 'net have not left me with anything very definite.
b) here's the tail output....

Thanks for any help anyone can offer!!!!!

Well, at least I have learned something. I had to look it up ... SFA means "Sweet F**k All", slang for "nothing" :-)
Keep in mind that I am not expert on this, just a user and an observer who tries to deduce causes of it all :-)
Your inability to read your media (properly) may have at least two causes: - media settings (faulty code) in your KDE I am a GNOME user, but you should be able to find it in KDE as well. It is about: File Management Preferences - Media - Media Handling Choose what happens when inserting media ... etc. - kernel scsi interface and driver problem
Also, you should test it (inserting and reading media) in both KDE and command line environment, while watching and documenting '# tail /var/log/messages' output after every event or entry: - KDE, under various media handling scenarios (see above) - in xterm only, using any combinations of entries e.g. a). do some basic scsi, drive, and driver checking (man wodim) # wodim -checkdrive # wodim -scanbus # wodim --devices etc b). then, insert your media # df pay attention to mount options ... # mount # umount /media/<whatever> # mount -t auto /dev/sr0 /media # ls /media/*
It would be good if you test your drive by preparing small iso file and burn a CD-RW disk (or CD-R if you want to be wasteful). This should also show you potential errors, and confirm if your drive is healthy or not.
Document action and faulty behavior/error output to be able to file a Bugzilla report, most probably to kernel scsi subsystem maintainers.
Btw, yesterday I was in trouble with my notebook CD/DVD R/W drive when I wanted to burn a CD-RW disk. I tried it with Brasero disk burner app - failure. I tried it with 'wodim' on the command line, even 'wodim -scanbus' told me to f*k off due to something like "... inability to recognize scsi interface or finding a driver ...". After rebooting I was able to make it work with wodim. I do not remember anything like that happening ever ... That tells me perhaps there is a common problem for all of us, and not specific to GNOME, KDE, or any of their applications, but rather to wodim or kernel scsi interface and drivers.
