## Almost PC compatible
|
|

|
|
|
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.
|
|
|
|
For some reason, occasionally formatting software will put an extra IDAM record
|
|
with a sector number of 66 on a disk, which can horribly confuse things. The
|
|
Atari profiles below are configured to ignore these.
|
|
|
|
Be aware that many PC drives (including mine) won't do the 82 track formats.
|
|
|
|
## Options
|
|
|
|
- Format variants:
|
|
- `360`: 360kB 3.5" 80-track 9-sector SSDD
|
|
- `370`: 370kB 3.5" 82-track 9-sector SSDD
|
|
- `400`: 400kB 3.5" 80-track 10-sector SSDD
|
|
- `410`: 410kB 3.5" 82-track 10-sector SSDD
|
|
- `720`: 720kB 3.5" 80-track 9-sector DSDD
|
|
- `740`: 740kB 3.5" 82-track 9-sector DSDD
|
|
- `800`: 800kB 3.5" 80-track 10-sector DSDD
|
|
- `820`: 820kB 3.5" 82-track 10-sector DSDD
|
|
|
