Is there any jumpers to set? I would think that the top one would be master and bottom would be slave, and one position would be master only.
Other than that I think, IIRC the A1200 can only recognize one IDE device. you may need a IDE buffered header, Amigakit sells a few different ones. The best one looks like the IDE fix express for the A1200, it lets you add up to 8 devices (not sure if its all at once).
