That is as it is. However, it that truely all there is?

This is not pulling your leg. I am actually considering this. What I am
thinking is that giving my using a 3Ware card combined with some rack
thingum with a key that electrically severs connections to power and
IDE bussed...

Given that I would create a MD somewhere with mount and umount tucked
into it... should it not be possible to umount, turn the switch, insert
a fresh disk and take it from there?

Whatever shape the IDE bus is in, it oughta be possible to whack it
into proper shape again. As long as you don't blow any necessary 
circuits unnecessarily it ought to be possible to get the show on
the road again.

Then again, this isn't intended usage.
