I once needed copy protection for a program, not for sale or general 
distribution but there had to be only ONE copy of the program. So what I did
was make a little hole in the disk with a needle, and then wrote a program that
would scan the disk to see which sector returns error when read, and then had 
my program check for that sector, to see if it was unreadable and check a few 
other sectors to make sure the entire disk was not damaged. It worked fine.
