Hi Michael,

I left out the option "-a" on running "cp" command.  Sorry.

Re-did following steps;

# 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

# mount new_cd_image.raw /mnt -o loop

# cp -a /home/satimis/Documents/FedoraCore3 /mnt/
# ls /mnt/
FedoraCore3  lost+found

The directory "FedoraCore3" was there.

# du -h new_cd_image.raw
651M    new_cd_image.raw

# du -sh /mnt/
568M    /mnt/

It showed the size of the directory copied onto it.


Burning CD:-
# cdrecord dev=ATA:1,0,0 speed=10 -tao -v -eject new_cd_image.raw
(Remark: tried both without "umount /mnt" and with "umount /mnt" before
burning, same result)

# umount /mnt

# 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

# mount -t ext2 /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,

Still could not mount the CD.
