On my Amiga 2000 (rev 4.2), both internal drives will spin if either drive
is commanded to spin.  However, the drive light of only the target drive
should light up.

The pin was not broken.  It is a "key" designed to prevent the plug from
being inserted incorrectly.  No signals are connected through that pin.
