BOTH LEDs should not turn on at the same time. That means that both of the drives are selected at the same time. I went through the same mess with the EPSON dual drive (3.5"/5.25). I finally figured out from trial and error what jumper settings worked. The issue I have seen with these and a few other drives is that the motherboard was made so it required a particular jumper arrangement for DS0/DS1/DS2, deliberately so that a normal drive would just not "drop in". Back in the day, manufacturers wanted you to buy their drive, not use someone elses.
