Steve,
 
Your disk drive is NOT, repeat NOT broken.  Nor is your motherboard.

Calm down, that's right.  Take a deep breath.  Calmer now?  Okay, onward...

Steve, the missing pin that you see on the disk drive connector is nothing 
other than the pin referenced as *KEY on the A2000 schematics.  Meaning, 
it's supposed to be missing.  The pin directly above it is pin 1, and is
where the red lead on the cable should go when you put it back.

Now, if you're still having trouble with your second drive (after placing the
jumper and replacing the drive cable), check the following:
 
1) Drive not accessing, or any disk put into drive shows up as NDOS:
   Means you forgot to connect the power lead.

2) Drive light constantly on:
   Means you have the ribbon cable on the back of the DRIVE plugged in
   backwards.  Reverse it and try again.
 
3) Both drive lights constantly on, or system refuses to recognize
EITHER drive:
   
   Means that the drive jumpers are set wrong.  If you have any documentation
   on your drive itself, change the drive jumper to drive select 2; if
   you don't know the proper jumper settings, don't play with 'em,
   esp. on the earlier drives.  You can make matters worse.  Take it to
   a reliable tech, and he'll take care of it for you.
