/dev/cdrom is not a valid block device
 

:Pengy: I´m usin Debian 3.0 woody r2 and i´m trying to mount my cdrom, but it doesn´t work. I´m getting the message: /dev/cdrom is not a valid block device. I updated my kernel to 2.4.23 in hope it will fix the problem, but the problem is also there. Can somebody help me?

Greetings from Germany!

Is there a CD in the drive? If yes, does it have data on it? Media must be in the drive for it to mount, and blank media cannot be mounted. Audio CDs also don't need to be mounted, iirc (I don't usually play audio CDs on my PC, so I'm not sure).

If none of these is the problem, what is the setting in /etc/fstab for this device? Please post the line here.

Are you using scsi-emulation or not? What device is /dev/cdrom pointing to? if you're using scsi-emu it will be something like /dev/scd0 instead of /dev/hdx. you can install sg3-utils and run sg_map to see what scsi devices are loaded. I'd check the symlinks and make sure /dev/cdrom is pointing to the right device

Yes, there is a data CD in the drive!

I will try this. My idea was the same that it depends on the scsi-emu. But i hadn´t any idea how to check this.

Thank you!

Here is my /etc/fstab

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/hdb2 / ext2 errors=remount-ro 0 1
/dev/hdb5 none swap sw 0 0
proc /proc proc defaults 0 0
/dev/fd0 /floppy auto user,noauto 0 0
/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0

Here is my /etc/fstab

# /etc/fstab: static file system information.

/dev/cdrom /cdrom iso9660 ro,user,noauto 0 0

ok... if you're using scsi-emulation your device will be something like /dev/scd0. if not it will be something like /dev/hdc.

do this..
mine looks like this
since it's pointing to /dev/cdrom0 I did the same thing on it
of course I don't use scsi-emulation. Once you find out the actual device.. try mounting it with (as root)

I think you need to make sure /dev/cdrom is a symlink to the right device

Hi there

I'm on my 3rd day of debian, but I have noticed on my install that I do not have a /dev/cdrom but I do have /cdrom.
Maybe try mounting /cdrom and see if that works ( it works for me ).
Still no cd audio though, am still huting for that one.
