[Coco] OS9 vs RSDOS disks

[George Ramsower]

 I apologize. I'm only a novice.  I see what you want to do and others have 
much more info on what to do in this case.
 It's just simply the way I do it! Otherwise, I reformat the darned disk and 
use it as a normal floppy.
 I suppose it would be cool to find out what the darned disk is.

 I'm watching to see how this turns out. I might be able to salvage a few 
disks in the future.

  George, I don't think you understand what I'm wanting to do or maybe I 
didn't explain it well. I want identify an OS9 or RSDOS disk from within an 
os9 program without using any outside utilities. Such as reading something 
maybe that is constant on LSN0 of an OS9 disk? not present? then RSDOS. I 
just don't know what to look for that would be a constant. I don't know 
enough about the os9 disk format system to know what LSN0 contains that 
maybe constant on ALL os9 disks.
  I would like for my program to ID the selected drive & disk and react 
accordingly.
