My understanding is that this is because copy-protected disks were written by the games manufacturers who used special equipment to write some track about 15% slower than usual. And because the Amiga has quite a good tolerance for reading but can only write at a constant speed these disks worked fine but could never be copied by any programs...
However, I'm sure somone will put me right if this is innacurate!
However, the best copier I ever used was Tetracopy - remember that one?
I'm getting an A500 soon and am keen to find a soloution if there is one - come on guys!
