CD/DVD Rom not working in Ubuntu 8.04 on Lenovo Ideapad Y710
Hello,
I have a Lenovo Ideapad Y710 and having problems with my CD/DVD drive.
After installed Hardy Heron the DVD drive stopped working in both Vista (pre-installed) and Ubuntu. Soon I figured out how to correct the problem in Vista (had to delete an entry in the registry) but could not correct it in Ubuntu. I am kinda new on Linux and I will appreciate any help.
It so pitty since all works well and its superafast laptop.
What is the drive not doing? It would help us if you provided a little more info. But for starters if it is not playing a music cd when inserted try opening up a terminal and typing the following.
Code:
sudo mount /dev/cdrom /media/cdrom
you might have to change cdrom to where it actually needs to be. Man I really need to get my vm up and running so that I can test other dist.
Hello and thanks for the post,
My case is not that easy. Its kinda weird.
When I try to mount it I get mount: special device /dev/cdrom does not exist.(Have tried all possible names)
The drive works for sure since I am using it on Vista and an Ubuntu VMWare workstation on the same laptop....! When I boot with the Ubuntu VM it mounts the cdrom automaticaly as normal.
So it is not working when boot with Grub.
And one more funny thing. Any CD/DVD rom does not work. I have also try with an external one and also did not showed up.
My question now is is it any way to go through the boot logs and see if there is an error message there.
Once again thanks.
Hello,
The log is to long to post in the Thread. It does not have anything obvious on it regarding the CD/DVD rom.
What I am looking for?
I believe the problem starts on the Laptopīs Bios but not 100% sure yet.
The old good days of IBM are over. Those new ones even they perform beptter than the ThinkPads they suck on Support. The BIOS is so poor for such a machine.
Thank you again.
If you have any idea please let me know.
Stef
Unfortunately there is nothing regarding the CD.
Thats very strange. Any ideas.
If the problem is the BIOS (not letting the drive to show up) then I should be able to do something with my external one.
you should have something in the logs if the system sees the drive. are you sure you looked at that log close enough ?
have you tried searching teh log for the DVD drive ?..
stefanos@Y710:~$ sg_map26 --result=2 --symlink /dev/cdrom
stat failed on /dev/cdrom: No such file or directory
Thats strange.
Keep in mind though that VMware workstation uses a virtual BIOS.
I will give you little more history of the setup.
When first installed Ubuntu I used grub as bootloader for both Vista and Ubuntu.
This had the result to disable the DVD or any DVD/CD on the system.
Could not use it in vista too. Then I used neogrub boot loader and booted from the Windows side. That gave me the hard drive back in Vista but not fixed the problem in Ubuntu.
So I have stack.
Thanks and I appreciate your help. Any ideas. If is not the BIOS then what else we can blame. Grub????? But Grub is used in both vm and real systems.

Ok my bad I will try to Clear it.
I have 2 ubuntu installations. The laptop is dual boot Vista/Ubuntu
and within Vista I have a VM Ubuntu.
The clean install has the DVD problem. The VM works fine exept compiz which was expected.
I hope this makes thinks clear.
Ok so that makes things a little more clear. So if we understand you the problem is with your actual Ubuntu installation, NOT the vm correct? If that is true then is the previous post about the dvd mounting under the VM or the Actual Installation?
