Sorry, you are confusing HD 5.25" with 3.5" HD (here we go again,
<sigh>!).
Besides, in my case I AM using an HD 3.5" drive, just in LD mode...
I believe that HD 3.5" drives switch write current based on the
opening indicating an HD disk. I think that will let you write non-HD
data on them. I don't know that it would be readable on an LD drive.
For 5.25" drives, the write current is selected by pin 2, set by the
controller based on what it thinks it is writing. You would have
to change the signal into pin 2 to write LD data on HD disks.
