It seems to work ok as long as the user accesses the respective drive
the correct way. Access it wrong and it craps out.

 Given the issue described, it is likely that either something in
Nitros9 
 got confused related to using two different methods to access the
same 
 "disk" or Nitros9 did something that confused the controller.

 Given the above statement, however, it seems pointless to have *both*

 the LBA driver and the floppy driver loaded. There's simply no need.
And 
 having only one or the other loaded would eliminate any possible 
 interactions between the different modes of access and it would
reduce 
 the search space for the solution if there is only one driver
involved.
