I believe disk optimizers and fixers like DI or Mace Remedy/Unfrag
will work, but the Spinrite manual mentions that controllers which
fool the machine into thinking its got fewer sectors/more cylinders
are incompatible with it (or the other way around..)  8-)

We managed to trash the second partition on a 60 Meg Priam drive 
which used EDVR.SYS with Spinrite....

Be careful with it.
