The media size not being a multiple of heads times sector (sic) is
normal, no insane, since the number of heads and sectors per track are
nominal and not all media sizes have enough factors to be divisible
by any possible and/or reasonable choices for the number of heads and
sectors, and not all ****ware is dumbed down to pretend that the media
size is smaller than it is so that it can have enough factors.
