CD drive

[god]

I decided to post here, because the problem escaleted in FC 2.

I have got a Samsung SN-324B Combo Drive in my notebook. I've the problem that I can't open CDs very often. I tried to mount manually but it doesn't help. The Drive-Manager of KDE 3.2 didn't help too. Sometimes I've to umount and sometimes not. This is very strange and I don't know what to do.
Is there a kernel option or something else?

In FC2 (and all 2.6 kernels) you must make sure that Grub is not booting with hda=ide-scsi or somesuch. The ide-scsi has been deprecated and so just remove this line from grub and reinstall: vim /etc/grub.conf and /sbin/grub-installer /dev/hd<a-z>

Also, try mounting your drive manually to see what error messages pop up: mount /dev/cdrom

Good Luck!

my grub.conf looks like this:

#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that
# all kernel and initrd paths are relative to /, eg.

mount /dev/hdc /mnt/cdrom shows this:

/dev/hdc: Eingabe-/Ausgabefehler
mount: blockorientiertes Gerät /dev/hdc ist schreibgeschützt, wird eingehängt im Nur-Lese-Modus
/dev/hdc: Eingabe-/Ausgabefehler
mount: /dev/hdc ist bereits eingehängt oder /mnt/cdrom wird gerade benutzt

i try to translate :-) :
/dev/hdc: I/O-Error
mount: block ?? device /dev/hdc is write protected and is mounted in read-only mode
/dev/hdc: I/O - Error
mount: /dev/hdc is already mounted or /mnt/cdrom is in use

I hope that I translated correct!

It sounds like it is already mounted and/or it is mounted in read only mode. Post your /etc/fstab and /etc/mtab here to see if that can clarify the situation a little better.

Can you also clarify the exact problem you are having as well? I don't know if I grasp the issue entirely, thx.

My exact problem is, that i can't mount my CD-Drive very often. It only works sometimes. If I start K3B, it freezes when it's searching for CD Drives!
I don't know what to do and I'm sure that I mount correctly.

/etc/mtab:

/dev/hda3 / ext3 rw 0 0
none /proc proc rw 0 0
none /sys sysfs rw 0 0
none /dev/pts devpts rw,gid=5,mode=620 0 0
none /dev/shm tmpfs rw 0 0
/dev/hda4 /home ext3 rw 0 0
/dev/hda1 /windows/C vfat rw,uid=500,gid=500 0 0
/dev/hda5 /windows/D vfat rw,uid=500,gid=500 0 0

/etc/fstab:
LABEL=/ / ext3 defaults 1 1
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
LABEL=/home /home ext3 defaults 1 2
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,unhide,user,kudzu,ro 0 0
/dev/hda1 /windows/C vfat defaults,uid=500,gid=500 0 0
/dev/hda5 /windows/D vfat defaults,uid=500,gid=500 0 0

Does anyone have a solution!

Hmm this is a Cdburner correct? In that case you don't want to have the entry ro as that means read only, that would explain why k3b is crashing (I guess) as it is a cd WRITING program.

Here is my fstab line for my cdburner if you wish to try this:
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0
Hmm, it seems that I have the ro line too... I guess try using my line instead of yours and see if that works and then try removing the ro. HTH
