In a first step, you may try to mount the RBF device with the "verbose" 
option. If this doesn't provide any more insight, remove all 
non-sharable content from the floppy (or, even better, format a fresh 
one), dump its content to a file, compress it and send it to me in a 
private email. I will then try to mount the file as a loopback device to 
find out why it can't be mounted.

Two other things that I remember from the old days when I used to work 
with OS-9 are:
1. The format may be so old that the "Cruz" cookie was not yet 
available. Try the "nomagic" mount option to work around this problem.
2. The floppy format may not be OS-9 but OS-9000 which is, as far a I 
remember, not compatible.

Hope this helps,
Carsten.
