Copy protection

Part of the copy-protection routine for the PC port of Agent USA relied on a clever attempt to socially-engineer crackers: The program attempted to see if sector 0 was writable, and if so, proceeded to write junk all over it, rendering the diskette unbootable. Why is this clever? Because the original factory diskette was write-protected (in fact, it lacked a notch completely) and the check would always fail on a factory original.
