anti-piracy revisited
Man, I've seen this before..
In the 80's software companies went to great lengths to copy protect their software (which in those days was distributed on 5 1/4" floppy discs).
All kinds of schemes were created.. one of the most common ones used was to write CRC (cyclic redundancy check) errors at known tracks on the disc. Off-the-shelf disc drives could not write such a track on the disc, and the software "looked" for those errors at the known locations and would malfunction if they were absent.
I had an Atari 800 computer at the time, with Atari 1050 disc drives. You could purchase a "Happy" modification for these drives which enabled them to write CRC errors. This defeated nearly every copy protection scheme in place at the time. Soon, software makers got clever and included code to detect the presence of the "Happy" modification in the drive. You know what happened next? Some folks installed a big, red toggle switch in their drive, which turned the Happy modification on or off. When software was trying to detect the Happy, you turned it off.
Eventually, the major players figured out that it was just escalating costs, and copy protection went the way of the Dodo for a long time.
Only when Microsoft started using Product Codes and such did we really return to attempted copy protection. I guess the music industry will have to learn this lesson the hard way.
That said, I personally own over 400 CD's. All purchased legitimately at retail or online stores. I'm not much into ripping, MP3 players or any of that. I like to read album liner notes and see the cover art etc. I guess I'm a throwback..
