Upgraded to Ubuntu 8.10 - CDROM is not working any longer

Asked by petra on 2008-11-12

After we upgraded our System 76 laptop to Ubuntu 8.10 our CDRom is not responding any longer, in the terminal it says:
 /media/cdrom' as device name but it is no block device
eject: unable to find or open device for: `cdrom'
Anybody else has this problem?

1. Please include your System76 model number. If you're not sure what it is, you can find it by going to System > Administration > System76 Driver.

2. Does your drive spin up when you put a DVD in it?

3. If your answer to #2 is yes, please try the following.
- Go to a terminal and enter this command: sudo gedit /etc/modules
-At the bottom of the resulting file, enter these lines...

libata
ata_piix
piix

- Save the file.
- Reboot your computer

Does that fix it?

If not, repeat step two and remove the three lines you added. Save. Reboot.

Hi Thomas,
Here is my laptop info - that's what you needed?

System Name: Pangolin Value
System Model: panv3
Processor: CPU Version
Memory: 1024248 kB
Hard Drive: 78 GB

I just did as you suggested and as I write this, my CD Rom drive is
working!!! At least it's extracting files! YEAH - so far so good!

Thanx a bunch!
Petra :-)

OK, good. I've seen this happen before with upgrades.
Let me know if you have any other issues.

Hi,
I have the same problem. The DVD is not working at all. Yes, it does spin up, but that is all.
When i run lshw there is no listing for cdrom or DVD. What will i need to do?

Thomas Aaron (tom-system76) said : #5

Did you try the steps listed above?
What System76 laptop model do you have?

bmanjb4u (bmanjb4u) said : #6

Sorry i dont have a System76 laptop. I have a Sony vgn-fw290. I tried your steps and
the cdrom works sometimes and other times not.

Thank you. We only support System76 laptops, so if the solution above doesn't work, I really have no way to do in-house testing to better help you.

However, if your problem is intermittent, it may be resolved by re-seating your dvd drive -- just remove it and then firmly press it back into place. If that doesn't work, your problem is almost certainly a bad dvd drive, and you probably should try replacing it.

Good Morning Tom and Ian,

I paid you a recent visit at the Parker Rd. office where Ian "re-imaged?", my Pangolin P6 to be "factory fresh", albeit with 10.10 not 9.10, and rid of Fedora. For this seemingly "magical feat" (to me anyway), I have nothing but thanks and praise. However, now the Dvd/Cd unit no longer works correctly. It registers a blank disc and acts like it will burn something (the ubuntu-10.04.1-desktop-amd64.iso for example), but errors at the very end. Won't load pictures and music burnt to disc in 10.04 with this very computer, although disc utility does detect an "unknown media type". I have all the restricted stuff to play dvds, etc, but they do the spin and die afore mentioned. Is the above solution still applicable to my computer and the 10.10 OS? After fruitless efforts to find a solution on the forums, I again come begging (metaphorically speaking) at your door. I'm attaching the brasero session log from the failed iso burn. Whatever more information you need, please ask. Although you may have to explain how to create/retreive it.

Thank you,

Richard A Bevis, <email address hidden>, Bluebearbevis

Sorry people,

I guess I don't know how to attach something to this?!?
