The problem you are running up against is almost certainly due to the different
data clock rate used by the two disk drives.  The 29 MB disk uses a slower
data rate plus a 6% missing sector to hide timing marks.  To change a it
may require some combination of new crystals, retuned PLL, and new ROMs.
I expect even Xerox would have a hard time changing it at this late date.
