HAHA those sneaky ADS techs. After a few hours of checking around, I realized that it was not a limitation of the chip, but rather the settings. And after even more scrounging around I was able to get a config changer to turn on the slave device (apparently the ADS techs didn't want customers to be able to have two drives). There is still the limitation that I can't have a CD-Rom and HD at the same time, because of the power limitation, but two HDs work flawlessly. Most likely will incorporate this into my previous mentioned mod, but may just do a perif mod and do new casing to accommodate the now available dual drives, either way it will be a while as I'm so busy right now.
P.S. If anyone wants details on this mod to do to their ADS or Oxford 911 chipset that is limited to one drive drop me an email and I'll try to get it together sooner.
It seems that the stress of two drives was too much for this setup. The power supply died not long after running both drives on one, but I've just gotten back around to this. So I have a few questions about running drives from a wall adapter:
For hard drives the molex setup is 12V, Gnd, Gnd, 5V. Is the 5V needed? If not a normal "wall wart" 12V would do?
But if all those are needed would you have to use both a 12V and a 5V adapter and wire it up separately?
Or what other options are there for a setup to power drives separately from an enclosure?
Thanks for the idea! I was able to jimmy-rig an old (85W maybe, not sure) ATX power supply, using a bit of wire and a light switch
Unfortunately this solution is pretty bulky. And I'm making a new double case out of plexi so the smaller the better. Was thinking of getting a mini-ATX PS. But before I do that wondering if you have any other ideas, as that would be sorta overkill for two drives.

Posssibly take a cheap external drive cabinet's power, add a Y-adaptor, and see if that will power it. Way smaller if you retrofit the board into something more appealing. Just a thought, but micro-ATX may prove easier depending on what you are doing.
