[Coco] No Nitr(OS-9) in this coco

[Diego Barizo]

No, that's not the case.
This same disk booted without issues a month or so ago, and was created 
in the CoCo from another Nitros-9 disk (that doesn't work now either)
And the same problem is present with original games disks, that I'm 
guessing are 35 tracks.
Thanks for trying anyway.
