dvd/cd-rom problem


I have a problem with a new system I built. I loaded opensuse 10.3, updated all. The problem is with the dvd/cd rom drives, they are seen when booting and when the system is up. But after awhile they disappear. I updated the motherboard bios. I've googled and I'm stuck. Any clues?

What happens when you put a known good CD or DVD into the drive, while the system is up?

Most modern distros will automatically recognize when a CD aor DVD is inserted. As a minimum, there should be a mount point already setup in /mnt or /media. If it does not automount, try--eg--"mount /media/cdrom".

Tried "mount /media/cdrom" and I get "mount: can't find /media/cdrom in /etc/fstab or /etc/mtab" I know this is a good cd because I can boot from it. I didn't think dvd/cd-rom was in fstab?

Then try something like "mount /dev/cdrom /media/cdrom". Your device will be something like /dev/cdrom (if it's a CD drive), or /dev/dvd (if it's a DVD drive). It may have a number or something after it, if you have more than one.

The "/media/cdrom" is whatever directory on your system you want to mount it to. Make sure it exists first, or pick another one that does.

Opened Konsole su'ed and typed "mount /dev/cdrom /media/cdrom"
the konsile is still hanging also tried mount /dev/cdrom0 /media/cdrom0

Thanks for your suggestions but I think I'm going to wait for 11.0 and try again.

I've got 10.3 running on at least a dozen boxes in my environment, with no problems at all.

First, what is your device name? Is it /dev/dvd, /dev/cdrom, etc.??
Second, is the directory for your mount-point there?

If you've got several CD or DVD drives, you have to specify the one with the disk in it. Also, are these IDE drives? Since they're 'disappearing', have you checked to see if the drives are set up correctly? The master/slave jumpers are in the right places?

Have you tried only plugging in one CD drive, to see what happens then?

I seem to be having a similar issue but I might have some more information.

The following is what showed up in /var/log/messages after the drive disappeared (in the middle of ripping a cd I should add).

Oh, and the single/only drive is a Samsung Writemaster that is actually using sata which I don't understand seeing the above but I built it myself so I know that's what it is. Meh, what do I know, I've only spent a few weeks trying to fix this.

I get this in /var/log/message

May 16 17:36:41 linux kernel: sr0: CDROM (ioctl) error, command: Test Unit Ready 00 00 00 00 00 00
May 16 17:36:41 linux kernel: sr: Sense Key : Aborted Command [current] [descriptor]
May 16 17:36:41 linux kernel: sr: Add. Sense: No additional sense information

It's very frustrating. The drives show up in the bios correctly.They also work on that other os, m$. They are dvd-ram drives by lite-on.

I solved this. It appears to be a problem with libata. I have to install with hwprobe=-modules.pata as a boot option to bypass libata and use the older method. Otherwise it thinks the dvd-rw drives are scsi. Both are ide. My hard drive is sata. Don't know if this is the sata bug or not? I tried fedora, kubuntu and ubuntu none of which I liked but all worked with the standard install.
