Back in the late 80's I had a Tandy Coco 1 that had a copy protected game called Dallas Quest. I spent some time copying all the sectors from the master to the copy, and it always got stuck on this one sector. I guessed that the game would check if that sector is readable before deciding it's an authentic disk. I tested that idea by writing a basic program to continually write to that sector, and I would randomly open the disk door to try to corrupt the write. Eventually it worked, I corrupted that sector, and it was unreadable. The game was able to run now on the copy.

In my case, the copy program would skip the bad sector, but I was able to use a sector editor to ready the bad sector with the original disk in place, then swap it out and write it back to the copy. Worked just fine. No idea why the sector editor was able to do that but the copy program wasn't.
