Could this be a situation similar to what the PC-Ditto people just issued
a patch for?  PC-Ditto (the IBM PC emulator for the ST) has its own drivers
for hard disks.  Apparently some versions of ST DMA port adaptor boards
are slower at responding to commands than others; in particular the PC-Ditto
note talked about older Supra boards.  PC-Ditto recently issued a patch
that changed timing parameters in their driver to make it work on Supra's.
