Hi Chad,

I usually mount the CD and estimate its file size with df, then unmount and
dd it. Something like:
mount /mnt/cdrom
df | grep /mnt/cdrom
umount /mnt/cdrom
dd if=/dev/cdrom of=Image.img bs=1k count=<size from df>
You could use a block size of 2k (CD block size is 2k) and divide the count
by 2, but I am not sure if this really improves performance. Wouldn't hurt
though.
Bye,
Leonard.
