That explains the *what* (sort of), but not the why.  Given that this

occurs on four different systems, with four different drives, with

upwards of eight different IDE cables (both 40- and 80-conductor), and

that it's across multiple releases and multiple CD's, there has to be

something I'm doing wrong.  I'm just at a loss as to what.
