If the drives had DS jumpers then you just switch them both (i.e. if 
they were both jumpered DS1, then jumper both DS0).

The drives would then look at the other select line, which would have 
the effect of swapping the drive letter.

I seem to remember doing that. Later on when drives were cost reduced to 
remove all the jumpers, then it's slightly more complicated.
