After I Installed DVD my CDROM stopped working

My Cdrom stoped working when I tried to install a new DVD player. Can't boot from either and can't play music. No movies too.

I am newbie but if u try kscd, when the player comes up click on extra and then
configure u will probably have a choice to pick from either cdrom ,dvd ,:media
device choose whatever. the other thing u might look at is when u boot up go
to set up and look an your bootsequence to make sure cdrom or dvd is first on
boot list. Good Luck

To boot from the devices, check out your BIOS settings to make sure they are correct for the new device configuration.

As for the linux access, did you update your fstab for the new configuration?

It really doesn't matter which drive is master.

I assume that your CDRW drive used to be the master so its device ID was /dev/hdc. /dev/cdrom is a symbolic link that points to /dev/hdc but now the drive is actually /dev/hdd. Delete the link and recreate it using /dev/hdd.
ln -s /dev/hdd /dev/cdrom

I've never used a DVDRAM drive but AFAIK it is just like writing to any other removable media. I believe the drive needs to be configured for SCSI emulation using the hdc=ide-scsi option in your bootloader. I believe the device will be /dev/scd0.

Thanks everybody.

dcg: In KsCD I only get to choose from media/CROM, no other players. The bootsequence is: CDROM, C, A. This used to work when all I had was CDROM. Thanks for your good wishes!

masonm: the Bios autodetecs the CDROM and DVD, and from what I can see it is OK. When you say BIOS setting for the new devices, do you mean addresses and such? I haven't made any changes in the BIOS other than chosing a bootsequence. As for the fstab, I must plead ignorance: I have no idea what that means or where I can find it. Is it anything I can update from KDE?

michaelk: it doesn't matter which is master and servant? Does that mean that the software will figure it out regardless of the devices master/slave jumper settings? Yes the CDRW used to be master but I don't remember what device id it had, it was probably /dev/hdc like you say, but I'm not 100% sure. When you say delete the link do you mean mounting? Could it be that the CDROM and DVD wass never mounted properly or not at all? But that does still not explain why I can't boot from the DVD player.... Here's my fstab:

the dev/cdrom is noauto, and maybe this would explain the errorcode I recently got from amaroK:

Quote:

Could not mount device.
The reported error was:
mount: only root can mount /dev/cdrom on /media/cdrom

I have a few things to try now...:study: amongst other things I suspect that the dvd is defect. Thanks again for your help.

I thought SCSI emulation was deprecieated? It couldn't hurt to have it in there, but the dvd burner normally shows up as /dev/scd0

You can use K3b, or any other program you use to burn data/audio cds. Or, through the console with growisofs or any of the other dvd burning tools.

deleting the smlink means :rm /dev/cdrom

change this line

Code:

/dev/cdrom /media/cdrom subfs noauto,fs=cdfss,ro,procuid,

and add users on the end.. like this

Code:

/dev/cdrom /media/cdrom subfs noauto,fs=cdfss,ro,procuid,users

this will all all users to mount.

Also, you might want to consider adding the dvd device manually. Does your distro automagically add things to the fstab? I've found that, sometimes, that stuff doesn't work right half the time.

Thanks DeusExLinux, i've just removed the DVDplayer to see if it really is defect. It won't boot, but when I physically replaced the DVD with the CDROM it booted just fine, like before, with the same settings. So I'll try it on another PC to make sure.

sounds like a plan
keep us updated!
