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.
No, high density 5.25" disks simply fail to work in my AppleDisk 5.25" drive. They won't format. I'm pretty sure that HD disks didn't exist when I got the drive, so I doubt it knows to check.
My comment would only apply to writing DD format in HD drives that allow that operation. It takes more write current to write to an HD disk, which is why it won't work in older (pre-HD) drives. -- glen
