It works for other systems because it performs low-level control of the Western Digital FDC and PC type floppy drives to re-create the format of those systems. Amiga doesn't have the same hardware setup since it's an Amiga FDC and slightly different drive. | |

Which is probably less than you'd get with ImageDisk, that's likely at least to provide data split into sectors with addresses and sizes. Though I think PC hardware with a single drive can't read the data between sectors, which the WD1772 in an Atari ST can to a limited extent, and you'll loose all timing information and any weak bits, and I don't know this tool specifically but declining to preserve sectors with bad CRCs is not uncommon. | |

The best raw dump tool is Linux block devices (part of every Unix systems) otherwise which allows devices to be read like normal files. The problem is not software, it is physicall. | |
