Everything you say about flux makes perfect sense. Flux is flux, however, I can't ignore my observations.
To test the theory of dirty drive heads, I simply made .scp images and duplicates of other types of disks. I've now made dozens of working copies of IBM 720K, IBM 1.44MB, and Macintosh 1.4MB disks, using both of my drives and index copy mode only. I then tried a couple Mac 800K disks, which invariably failed. To humor the cleaning idea, I cleaned the SD-800's heads, but the 800K disks still failed. Surely it doesn't make sense that 800K disk don't work due to dirty heads, but all of those other formats somehow do.
Can you tell me a specific model of any drive that has been reported to work with Macintosh LD disks, or perhaps one that you have used? I seem to have no other option than to try drives that are known to work, empirically speaking.
