How can I determine CD Serial Number before I burnt it

[Lil Half Swell]

Just my 2 cents worth, but your time would be better spent if you avoided trying to copy protect your CD. There will always be a way around it anyway, and all that time you spent trying to protect it will be wasted. You may stop or slow down less experienced people, but anyone who's been around the CD-burning block for awhile won't be fooled.
