LG CD Burner problem with Mandrake 10 Official

Hi folks.
I've finally switched completely over to Linux due to good luck finding printer drivers for my Lexmark X75, but now I have a completely different problem.
I have used Mandrake 10 on my machine several different times, and have never had this issue before.  
I am using 2 almost identical LG CD-R drives... one is 12x8x32x, and the other is 16x10x40x.
I first noticed a problem while trying to listen to an audio cd while doing some office work, but my drives wouldn't mount the cd.  I tried several different cd's, but then found a way around my problem. I recently downloaded a firewall/antivirus program, and now i can't burn the program to cd.
I tried disconnecting one of the drives (last time i used linux, i only had one drive), but that did not help at all.  
I also searched some help forums on the net for LG problems with Mandrake, but no luck.  The burning programs i am using are GToaster and K3b.  Neither program can find my cd drives, which i know work.... because i installed linux...  :)

Any help would be greatly appreciated.

Thanks

> I first noticed a problem while trying to listen to an audio cd while doing some office work ...
Are the CD(s) "copy controlled"? Might make some tracks/the whole disk unreadable...

About the burners... The Mdk installer had some issues with some LG drives, since LG used an idiotic method to initiate a firmware update ... effectively abusing the SCSI "standard"... So that when the installer probed for possible CD drives, it effectively set them up for receiving a firmware update.... that never came. This is not your issue:-).

What does
cdrecord -scanbus
give?

hmm... when i do the cdrecord -scanbus command it shows both drives as they should be shown.. but i still don't know what to do to correctly configure my computer to allow audio cd playback / recording, or any other cd drive actions...

Ok, so you cannot play any CDs? Hm, if you are using ALSA for your soundcard (which is rather likely) you'd need check with a mixer application (kmix will do) that the "CD channel" is unmuted, and that the volume is raised (on the "channel")... You have connected 'em to the soundcard, right?
And remember, some copy-controlled audio CDs will not be recognized by some CD drives... Not as anything but "a shiny bit of plastic":-).

GToaster and K3b is more like nice wrappers around a cdrecord core, so you could try verifying the "burnability" by using cdrecord to burn an ISO (or some .wav files) onto a CD-R. Use the info from "cdrecord -scanbus" ... it tells you the SCSI bus, target and lun, so that you could do something like:
cdrecord -v device=0,2,0 driveropts=burnproof -eject /path/to/file.iso
... Which is to say "burn file /path/to/file.iso onto the device on bus 0, target 2, LUN 0 in a 'talkative way' with the driver option 'burnproof' turned on. Eject the media after the burn process completes"...
Does this work? With both drives?

the problem is uncertain.  My soundcard is correctly configured, and my cd channel is unmuted, but i can't even mount the cd's.  Like i said, i know it's not the cd drives, because i've tested them and they work fine.  
One of the things i want to accomplish is ripping all of my MP3s to my computer, and i can't even get that far.
Btw, the cdrecord-scanbus shows all of my hardware as it should be shown, so it IS correctly configured, (at least i think so)  :)

Thanks..

Ok, first up: You can only mount a data CD, not audio tracks. For the "unplayability" of the drives... Did you check that they are correctly attached to the soundcard?

For ripping: Again, the GUI programs are very nice, but you could probably see them as wrappers there too (this time to programs like cdparanoia). Try running cdparanoia on an audio CD... Does that work? (read the cdparanoia man-page, it has a lot of nice options:-).

About burning: Do try the cdrecord command, it might well reveal any problems in that regard.

I've done exactly this numerous time (riping to MP3, then burning....), and one of the nicest ripping tools/wrappers there is, is grip.
For mp3 encoding you'll need get bladeenc or lame or somesuch. Due to copyright issues and legislation in a lot of contries these are never part of a linux distro, but need be gotten installed separately. To my knowledge the only lossy audio-compresser that'll be installed is oggenc... and that'll produce OGGs;-)
