~# chmod 777 /dev/scd

~# ls -l /dev/scd
brwxrwxrwx 1 root cdrom 11, 0 2007-04-18 09:48 /dev/scd

~# dd if=/dev/zero of=/dev/scd
dd: writing to `/dev/scd': No space left on device
19497+0 records in
19496+0 records out
9981952 bytes (10 MB) copied, 0.101183 seconds, 98.7 MB/s

That dd command should work right? I must be missing something, its not 
working.

Then if I do scd0 which has chmod 777 also...

~# dd if=/dev/zero of=/dev/scd0
dd: opening `/dev/scd0': Read-only file system
