I've recently noticed that i can't mount cdroms anymore .. apparently the device isnt in /dev anymore ..
devfsd.conf does have lines for cdroms so i don't really know where to look next ..
The drive is a toshiba IDE cdrw/dvd combo

sounds like a software problem.
1) possible driver issues. Did you recently install a new kernel? did you compile support for your drive for this kernel, or as a module, build the modules?.
2) something deleted your driver
3) something deleted your /dev file for the object
4) something deleted your /mnt directry
5) something modified your /etc/fstab to no longer mount the device or mount it incorrectly
Does the device work under a different operating system or a Gentoo or Knoppix livecd?

I have support for enhanced IDE compiled in .. and i havn't compiled a new kernel since the last time it worked.
2) something deleted your driver
I guess that isnt an issue according to #1
3) something deleted your /dev file for the object
Gentoo uses devfs right? That means it makes the device files automatically? I dont really know how devfs works, it just worked fine until recently.
4) something deleted your /mnt directry
nope
5) something modified your /etc/fstab to no longer mount the device or mount it incorrectly
The line for the cdrom looks perfectly fine .. but it tries to use the /dev/cdroms/cdrom0 which isn't there anymore.
Dual booting to winxp implies the drive works just fine. I emerged k3b recently and let it modify my fstab .. but i went over fstab and it doesnt seem bad. The drive is not supported by k3b yet, some of the older models in the same series are supported read only. |

|

If you pass"hdc=ide-scsi" to your kernel at boot (common for cd burners) and do not have "sg" and/or "ide-scsi" in /etc/modules.autoload then the device will not be created until the ide-scsi module is loaded.
You can see the kernel command line with:
If you see hdX=ide-scsi somewhere in the line try as root:
| Code: | modprobe sg
modprobe ide-scsi |
If you device appears after the modprobe then edit /etc/modules.autoload and add:
hope that helps |
