The cables were not wrong. Those were the cables that came with the equipment and would work perfectly if their connectors could be connected to the drives in the order they were mounted. Not in the unnatural order required to satisfy the "twisted" standard. Yes, the cases were cheap Chinese design. Unfortunately it was what 95% of people were buying those days. If they were of better quality, it would possibly help avoiding the injuries but not that much the connection problems. I still have a small pile of floppy cables and a drawer of those IDC connectors (both the "edge" and "goldpin") somewhere. A bad reminder of the times, when I never knew when I'd need them urgently ;-)

It was IBM. IBM was big enough already at the time they endowed the world with "PC", wasn't it? Being as big as they were, I bet they could (at no cost) make the drives manufacturer add a simple gate to the /drives'/ electronics. If I am not mistaken now, one (1!) transistor would do. And I bet again every drive manufacturer would bow to IBMs order as there were not that many customers for their products that could buy stuff in quantities.

Then we wouldn't have problems with Amiga drives being "non-standard" (except the 3.5 HD ones, that is) etc.

The above. At least one.
