This is my favorite part (emphasis is mine):
AmigaOS always supported 2 devices on the IDE port. To be able to
use 4, a third party software patch called IDEFix was often used. The
problem is that the IDEFix software does not work correctly under many
OS versions. In fact, on many scenarios, it will most likely fail.
Yeah, under 3.1.4 and 3.2. Translation: we broke compatibility with IDEFix

AtapiMagic has been tested working under both AmigaOS 3.1.4 and
AmigaOS 3.2. That said, under a few unknown circumstances, it seems it
may not work according to a small amount of reports received.
This sounds like some Apple press release after they got sued for some hardware issue
