Unhappy Cant use CDROM drive


I cant mount any cdroms, when i try 'mount /dev/cdrom /mnt/cdrom' i get a message telling me that the device /dev/cdrom doent exist, i get the same error if i replace /dev/cdrom w/ /dev/hdc, i have one cdrom reader and it worked great w/ the gentoo livecd (i use gentoo) and it also works great in Red Hat linux 9, any ideas?

Did u check your configuration to make sure the CDrom is visible? Is there a disk in the cdrom?

I dont know about gentoo but there should be a configuration setting or hardware browser that shows all your drives and other stuff so you can determine what hardware is on your machine.

okay try this,

boot from your live cd.

when it shows you the scrollbar and the gentoo logo press f2, and check the device name the cd finds , then try that.

you have to be fast

Hmmm... I'm not sure if these ideas will help but they might. Firstly, do you have permission to mount the cdrom? Try mounting it as root. If that succeeds add your username to the "cdrom" group. Secondly, try specifying a filesystem type (ie type "mount -t iso9660 /dev/cdrom /mnt/cdrom". Thirdly, check the /dev/cdrom symlink to double check where it's pointing to. Fourthly, it may be that your fstab is set up correctly but you're bypassing it. Try just typing "mount /mnt/cdrom" (ie just specifiy the mount point) or check your /etc/fstab file to see what the mount point is if it isn't /mnt/cdrom. If all that fails then you said that the gentoo live cd works, right? Boot that and pillage the /etc/fstab file. Once that's on your hard drive, type "mount /mnt/cdrom" or whatever the specified mount point is.

Just so you know, the fstab file is divided up into the following fields:

<file system> <mount point> <filesystem type> <options> <dump> <pass>

and they're usually separated by spaces or tabs. Tabs are nice because then everything is easy to read.

Hmm.. this has happened to me while using Mandrake 9.1. It seems they are copying solaris and hpux's way of device file naming and they are using /dev/ide/host*/bus*/target*/lun*

You might want to look for that for your CD and do a soft link to /dev/cdrom to the correct path.
