CD ROM mount error: "no medium found"?????

RonRussell · 06-28-2002, 08:22 PM

I'm running Suse 7.1 on a 900 Mhz Celeron, with a CD-ROM as master on it's own channel, and a CD-RW as slave on the same channel as the hard drive. When attempting to mount either device, I receive the error message "No Medium Found".
What does this mean, and how do I fix it?

Did you put a disk into the drives before mounting them?

Yeah, it seems a little odd, I assume you did put disc in the drive - are there any scratches on the disc - that sort of error indicates that a disc is not readable or it is not in the drive, another option ... well, the drive retired.

Installing a disc DID make a difference.....now I receive an error message 'input/output error: could not determine filesystem type, and none was specified'.
What does this mean?
The disc plays fine in the SAME drive when I boot that OTHER operating system, so I'm assuming that the problem involves some setting in the Linux OS.

Is it an audio CD?

As neo77777 points out, you can't mount an audio cd. Only data cd's.

Try mounting the cdrom drive like this:

mount -t iso9660 <device_name_here> <mount_point_here>

The -t iso9660 specifies the file type.

can you get to a shell? if you can, at the prompt: (assuming you're root)

[root@server]# lsmod

you will see a list of modules or drivers that are loaded. if you don't see a "cdrom" driver loaded find your cd-rom driver by typing:

[root@server]# find / -name cdrom.o

after find displays the location of the cdrom.o driver, at a prompt type:

[root@server]# insmod <location-of-driver>

then try to mount your cdrom.

if that doesn't work, please e-mail me with any errors or problems.

Yes, the disc is an audio CD. I had no idea that mounting audio CD's was not possible. I thought that any CD had to be mounted.

Thanks

No, audio CD's cannot be mounted due to lack of file system - they simply have none.
