DOS can only accept a maximum of 1024 cylinders on a disk.  If you have
more then that would explain your problem.  The solution is to get a disk
controller which does TRANSLATION.  This controller will make DOS believe
that your disk has less cylinderss and more sectors per track.  This
translation is transparent to DOS and will require only the proper low
level formating of the disk.
