Hi,
I would give it a try with the hdd auto detection set to off. I don't think the bios will disable the ide port.
Are you sure that you can't select a harddisk type on the first screen of your bios setup. (The screen that also has the clock settings.) Normally you have another setting somewhere in the advanced chipset setup to disable your primary and (or) secundary ide controller.
I am not a big expert in hotswapping techniques. I build myself a xbox eeprom reader so that I can connect the xbox disk safely to the pc (with the power switched off.) It's not so difficult to build, just a couple of resistors and zener diodes. You can use some dos tools to unlock the harddisk. I am not sure if your pc would allow to unlock the harddisk in dos.
If I would stand in your situation, and I wouldn't have another brand of pc to test it again, it is the way I would proceed. Just take a look at it and see for yourself.
