Re-creating legacy floppy file system, doable?

I'd like to be able to format floppys and read/write files to them in an old legacy format. I don't really know what would be the best way to acheive this. I'm thinking of making a hexdump of an empty disk in said format, then try to see some pattern in there as well as eventual revealing strings but apart from that I don't really know. I'm thinking of using fuse to implement it, if I'm able to figure it out.

If anyone have any ideas or general thoughts about how this could be done I'd like to know.

Thanks
