 Posted: Tue Jun 08, 2004 4:47 am Post subject: CD-RW Recognized but will not see CD-ROM |
 |
|
I have spent numerous days trying to figure this one out. After searching high and low in the forums I finally got my DVD working and the k3bsetup to recognize my CD-RW. The CD-RW drive is fine but it refuses to mount anything. I installed Gentoo using this drive, so it has to be some other error. Additionally, the DVD can play DVD movies and recognize data cdroms but it will not mount music cdroms.
I have tried adding ide-scsi to grub.conf but this makes the hdb and hdc devices inactive and the /dev/cdroms directory go away without adding any scsi drive devices.
(Side note: when I reboot my system several times in a row the font becomes super small. It will revert back to normal after a reboot. Any ideas why?)
Update: I am now able to access the CD-RW. I just mapped it to /dev/cdroms/cdrom1 and this worked fine. So now I get it to recognize data cdroms but music is still out of the question. K3B on the other hand will only recognize the CD-RW as root. I'll have to read through the docs to try and solve that one.
So, right now I need to know why I can mount everything EXCEPT music cdroms. I have included the new /etc/fstab below.
Thanks,
Cutaway

| You don't need to mount music CD-ROMs. You just play them or rip them with a cd player or grip.... You only need to mount something to access its filesystem and AFAIK, there is no filesystem on a music CD, it's just one giant wav file after another. |

Okay, I never noticed that. Thank you very much.
Update: Okay, I tried that but it does not work the way you say it does. Nothing recognizes music cdroms. I put them in the drive and nothing. They will not mount. Even when I reference the disc in k3b it shows the tracks but the are grayed out as unselectable (which is really weird because it shows track length and everything). This does not happen for data cdroms and I have tried more then one music cdrom to the same effect. When I open a media player and try to point to the cdrom it doesn't see anything.
I have udf,iso9660 selected in the /etc/fstab. Do I need something else for the system to recognize music cdroms? Is it a kernel issue (doubt it but need to ask)?
What a burn, I have no idea why this has turned out to be so hard. I have never had this problem with any other distro. I haven't even had to think about it (which is why I guess I don't know enough to fix it).

I had the same problem... so I looked through "emerge search cd" and found that I didn't have "libcdaudio" installed...
Once I did an "emerge libcdaudio" it fixed my problem (through xmms... I still haven't gotten it to work for my gnome-cd program).
Hope that helps
By the way, you have to emerge xmms-cdread to have xmms see music CD's. |
