[Coco] DSK files to real 3.5" disks

[Diego Barizo]

I just got a 3.5" drive to format disks and give me back a nice empty 
listing after a DIR.
Now I want to transfer some DSK files to real disks.
I just tried using DSKINI.EXE ,just as I did many times with 5.25" disks.
But it just won't work. I keep getting write error on track 0 , head 0, 
sector 1.
I used the same disk that the CoCo formatted, and also tried with 
another 2 that have MS-DOS fat.
All the same.
Is there something I must change somewhere? Or DSKINI just won't work 
with 3.5" disks?
