[cctalk] Re: Double Density 3.5" Floppy Disks

A 720K 3.5" is about 600 Oersted; a 1.4M 3.5" is about 720-750 Oersted. You can format a 1.4M as 720K, and often, maybe even usually, get away with it; it will be just like a poor quality 720K. On drives with a media sensor, you can cover the hole during formatting.
