[Coco] OS9 vs RSDOS disks

[Bill Pierce]

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.

 I forgot to mention that if there is only data or programs on it, you 
should boot OS9 and THEN dir the disk. If it's an OS9 disk, you should get 
info. Otherwise, it's corrupted or an RSDOS disk.

  Hi guys,
  Is there a simple way to tell an OS9 disk from an RSDOS disk? Maybe 
something constant in LSN0 on the OS9 disk?
  It would be nice to identify the disks through software

  Thanks
