Disk: Atari ST

Atari ST disks are standard MFM encoded IBM scheme disks without an IAM header. Disks are typically formatted 512 bytes per sector with between 9-10 (sometimes 11!) sectors per track and 80-82 tracks per side.

Reading disks

Just do:

fluxengine read atarist

...and you'll end up with an atarist.st file. The size of the disk image will vary depending on the format. This is an alias for fluxengine read ibm with preconfigured parameters.

Writing disks

FluxEngine can also write Atari ST scheme disks.

The syntax is:

fluxengine write <format> -i input.st

<format> can be one of these:

  • atarist360: a 360kB 3.5" disk, with 80 cylinders, 1 side, and 9 sectors per track.
  • atarist370: a 370kB 3.5" disk, with 82 cylinders, 1 side, and 9 sectors per track.
  • atarist400: a 400kB 3.5" disk, with 80 cylinders, 1 side, and 10 sectors per track.
  • atarist410: a 410kB 3.5" disk, with 82 cylinders, 1 side, and 10 sectors per track.
  • atarist720: a 720kB 3.5" disk, with 80 cylinders, 2 sides, and 9 sectors per track.
  • atarist740: a 740kB 3.5" disk, with 82 cylinders, 2 sides, and 9 sectors per track.
  • atarist800: a 800kB 3.5" disk, with 80 cylinders, 2 sides, and 10 sectors per track.
  • atarist820: a 820kB 3.5" disk, with 82 cylinders, 2 sides, and 10 sectors per track.

See the IBM format documentation for more information.
