- When you format more than 15 sectors per track, the inter sector
- gaps get too small for the disk drive to read the next sector in
- sequence ( resulting in another revolution), so FDFormat makes use
- of interleaving to create larger intersector 'gaps'. I'm using
- 800K for any none standard disks (FDRead hangs my system (DOS5.0)
- when there's no disk in the floppy and I try to access it), FDFormat
- Didn't gave me ANY PROBLEMS, so I presume there's problems with
- DR-DOS6.0 & sector interleaving on floppies.
