Tks for your advice.
1) dd if=/dev/zero of=new_cd_image.raw bs=1M count=650
2) mkfs.ext2 -b 1024 -m 0 new_cd_image.raw
3) mount new_cd_image.raw /mnt -o loop
4) Copy your stuff onto it
5) Burn the RAW image onto CD
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

(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/

To my surprize, there was nothing inside
Because you didn't copy anything onto it, see above, cp failed.
# 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
Why? your cp failed. you've just a 650MB file of zeroes.
# cdrecord dev=ATA:1,0,0 speed=10 -v -eject new_cd_image.raw

# 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.
/dev/hdc is going to default to iso9660, and /mnt/cdrwriter also has to
exist....so assuming it does
mount -t ext2 /dev/hdc /mnt/cdwriter
