Bob,

I think you have an intermediate update of NitrOS-9. Some changes have been made 
to rb1773 intended to prevent problems writing to disks formatted differently 
from what a specific floppy drive can handle. Basically a mismatch between disk 
format and descriptor values.
You seem to have created 96tpi disks without having the newest rb1773 driver and 
that is preventing you from reading the disks.

I just tested both MESS and VCC using the newest rb1773 with both DD.FMT 48tpi 
and 96tpi and the disks boot correctly.

I had thought the repository was updated for the new rb1773, so don't know why 
you are having problems.
