Reminds me of the good old days of pirating Atari programs, creating
bad sectors to bypass copy protection schemes. Everything from
tugging on tape attached to the floppy while using a "GUI" format tool
to using programs written to create the bad sectors.

Do a search on www.astalavista.com for "creating bad sectors". Old
cracking guides will discuss how to create them. This search also
works:
