I remember the Dungeon Master copy protection. Its weakness was that if the game was even only partially cracked, you'd still have some time to advance the game before the copy protection kicked in and it crashed or killed you so we got pretty far by sheer stamina. Luckily we as kids had a lot of time available for waiting the game to load over and over again. And it _was_ that good of a game even in retrospect.

I also successfully managed to pirate an original Chaos Strikes Back disks by repeatedly copying the data with a (pirated) synchronisation dongle and the Cyclone software. It required several attempts to get the fuzzy sectors correct because I was using a pre-used disk. This technique and the recommendation to use completely blank disks would have been mentioned in the manual of Cyclone but I wasn't aware of it... Since I'd also pirated the software! I was also unaware of the fuzzy bits themselves, so it was just a bit of luck.

Anyway, CSB wasn't as exciting experience as its predecessor. Boring maze-like transforming levels, hard monsters (in the sense that they took a lot of time, not skill to eradicate), little of anything new, etc. Disappointing after all that effort ;)
