I had the same thing happen to me, except that both of my drives still worked.
I suspected that the pin might be cut at the factory, to make it harder to
to connect the drive cable incorrectly. However, even though I could read
and write from both of the drives, one was always spinning and always had the
busy light on. Checking the schematics, it looks like the pin that broke on
mine (which I think is the same as in your diagram, I don't have my Amiga
handy at the moment) is a Drive Select pin. I managed to temporarily solve
the problem by pulling the broken stub of the pin out of the cable a bit,
and pressing the connector down very firmly. This has kept things normal
for the past 2 months, and through several long distance car trips, so
maybe I'm lucky, or maybe this wasn't the cause of my problem. It certainly
is easier to give it a try than to replace the entire connector (which would
seem to be virtually impossible, especially without screwing up other
things). If that doesn't work, you might be able to connect a jumper from
the trace on the board to the correct wire in the cable. In any case, good
luck.
