Chances are it is due to the STUPID_WINI_ADJUST problem.  MINIX expects 
blocks to begin at even sectors.  MS-DOS does not.  That was always solved
in an ad hoc way before.  Now Bruce has solved it in a very nice way by
providing commands in fdisk to manipulate the origin and size of partitions.
Take a good look at fdisk.
