Tks for your advice.

I tried the steps but did succeed. I made the test on a FC3 PC on
another location as I did not have a Knoppix LiveCD 4.0.2 in hand.
Steps performed as follows;
# dd if=/dev/zero of=new_cd_image.raw bs=1M count=650
650+0 records in
650+0 records out
# mkfs -t ext3 -b 1024 -m 0 new_cd_image.raw
mke2fs 1.38 (30-Jun-2005)
new_cd_image.raw is not a block special device.
Proceed anyway? (y,n) y

This filesystem will be automatically checked every 34 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
(Remark: the files to be copied on a partition of fs ext3
also tested "mkfs.ext2 -b 1024 -m 0 new_cd_image.raw"
with the same result, not successful)
# cp /home/satimis/Documents/FedoraCore3/ /mnt/
cp: omitting directory `/home/satimis/Documents/FedoraCore3/'

# ls -al /mnt/

To my surprize, there was nothing inside
# ls /mnt/new_cd_image.raw
ls: /mnt/new_cd_image.raw: No such file or directory
# umount /mnt/
# du -h new_cd_image.raw
(Remark: Also tested without "umount /mnt". Same result,
Continued burning CD
# cdrecord dev=ATA:1,0,0 speed=10 -v -eject new_cd_image.raw
Average write speed 9.9x.
Min drive buffer fill was 98%
Fixating time: 26.990s
cdrecord: fifo had 10736 puts and 10736 gets.
cdrecord: fifo was 0 times empty and 10467 times full, min fill was
# mount /dev/hdc /mnt/cdwriter
mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
or too many mounted file systems
Please check that the disk is entered correctly.
I could not read the CD. Whether the steps only work on Knoppix
