## Acorn Atom, BBC Micro series
|

Acorn DFS disks are used by the Acorn Atom and BBC Micro series of computers.
|
|
They are pretty standard FM encoded IBM scheme disks, with 256-sectors and
|
|
0-based sector identifiers. There's nothing particularly special here.
|
|
|
|
DFS disks are all single-sided, but allow the other side of the disk to be
|
|
used as another volume.
|
|
|
|
They come in two varieties, 40 track and 80 track. These should both work.
|
|
Some rare disks are both at the same time. FluxEngine can read these but it
|
|
requires a bit of fiddling as they have the same tracks on twice.
|
|
|
|
## Options
|
|
|
|
- Format variants:
|
|
- `100`: 100kB 40-track SSSD
|
|
- `200`: 200kB 80-track SSSD
|
|
|
|
