(MS)DOS floppies on PCs are never setup with hard sectors.
Yet they are so darn prevelent.
Don't you really mean hard sectored floppies WERE so darn prevalent way back in days of yore... BEFORE MS-DOS became so darn prevalent? 

Hmmmm..... ok...

One little question, why does High Density 1.2 MB disks not format on a Commodore when doing a format ? (maybe soon, I would be best to have a modified Commodore controller that will support the 1.2 MB disks and modified DOS





Because it takes more than 2 times more current to change the polarity of the magnetic material on HD media. This is only on 5.25, as 3.5 drives/disks don't have this problem.
