Exclamation CD Drives not working in Slackware 9.1

I've just changed my Yamaha CD-RW for a LG CD-RW (8081B) and a Samsung CD drive. I can't mount CDs in the drives or play audio CDs.
Here is my dmesg:

what errors do you get on " mount /mnt/cdrom " or " mount /mnt/cdrw " ?

Hi, Can you mount them when you are logged in as root? Could be a permission problem. I wonder if you have to remove the "owner" parameter from /etc/fstab?

Thanks - I'll try that. I'm away from my Linux PC at the moment but I'll try it tomorrow.

Hi again,
I've tried mounting as root and removing owner and it still doesn't work. The error messages are:
root@linux:/mnt# mount /mnt/cdrw
mount: No medium found

root@linux:/mnt# mount /mnt/cdrom
mount: Not a directory

do you have a music-cd in the drive ?
if so, use a data-cd; music-cd's don't have a file-system so they cannot be mounted.

and do you have a mount-point " /mnt/cdrom " ?
if not create it with " #mkdir /mnt/cdrom " ( it's just an empty dir. )

The mount point exists and I was trying to mount a data CD which I had used before with my old CD drive.

I would check those things
-- replacing the occourence of scd0 with sr0 in your /etc/fstab.
-- removing the "owner" option from the lines containing "scd0" and "hdb"
-- try mounting those devices with the command
mount -t iso9660 /dev/sr0 /mnt/cdrw
mount -t iso9660 /dev/hdb /mnt/cdrom
Hope this helps

As root, try 'mount /dev/cdrom' (instead of mount /mnt/cdrom) to gain access to /mnt/cdwhatever. At least that's what works on my Slack system.

Edit: Whoops, never mind. Judging by your fstab you should 'mount /dev/scd0' for access to /mnt/cdrw or for the other drive, 'mount /dev/hdb' for access to /mnt/cdrom.

I'm probably wrong though.

bash-2.05b# mount cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems

egag mentioned something about music cds not having a file system. how can i play music cds? the cdrom mounts data cds just fine

To play CDs use a cdplayer like kscd. I'm away from my PC at the moment again but I'll try out your ideas when I get back home.

Thanks for all your help


EDIT: I tried to burn a CD and it didn't work
