How do I get CDRW and DVDROM to work?

I am running Debian Sarge with kernel 2.6.6. When I put knoppix in, it says my cdrw is scd0.

Here is my fstab:
/dev/hdc2 none swap sw 0 0
/dev/hdc1 /boot ext3 defaults 0 2
/dev/hdc5 / ext3 defaults,errors=remount-ro 0 1
/dev/scd0 /dev/cdrom iso9660 defaults,ro,user,noauto 0 0
/dev/fd0 /media/floppy auto rw,user,noauto 0 0
/dev/pilot /pilot defaults,ro,user,noauto 0 0

I did: mount /dev/scd0 -t iso9660 /mnt/cdrw
and I got: mount point /mnt/cdrw does not exist

I cannot get my floppy, dvd, or palm to work either.

make sure the mount points are intact
mkdir /mnt/cdrw
and so on.
Also the following entry in your fstab looks out of place
/dev/scd0 /dev/cdrom iso9660 defaults,ro,user,noauto 0 0

the only way /mnt/cdrw exists if if you manually created it. Did you?...

The fstab mounts it at /mnt/cdrom. you are of course free to change it to cdrw if you wish, but it makes no difference.

Thanks, well I got a little farther.

I did:
mkdir /mnt/cdrw

mount /dev/scd0 -t iso9660 /mnt/cdrw

And got this:
mount: /dev/scd0 is not a valid block device

I changed /dev/scd0 /dev/cdrom iso9660 defaults,ro,user,noauto 0 0 to this:
/dev/scd0 /dev/cdrw iso9660 defaults,ro,user,noauto 0 0

Why do I get that? When I load knoppix it says my cdrw is scd0. I don't understand...

Bump, anyone know why it says

/dev/scd0 is not a valid block device

Probably because it's not using scd0. Try looking at /dev/cdrom and see where it points to. If it doesn't exist, make a symbolic link to /dev/bus/ide/.....can't remember the rest right now. But it might be using the IDE bus and not the scsi. Does for me any way. And use cdrdao-1.18 for burning. It has IDE support rather than using scsi. I had to figure all of this stuff out the hard way in 64bit. :-)
