Greaseweazle: Tools for accessing a floppy drive at the raw flux level
- dakiol 2y agoWhat is "flux"? It's all over the source code.
- actionfromafar 2y agoThe magnetic variations on the diskette are called flux in this context.
- udevrandom 2y agoIt’s the actual raw magnetic field changes encoded in the platter. It matters because lots of floppy setups had “anti copying” setups which played tricks on readers, or where degradation over time means the peaks and valleys of 1/0 can become less pronounced. Thus getting at the core flux can help with retrieval and fixing

Mostly not tested yet. I have some of each of the different kinds of drives but haven't finished the project of fabricating nice drive enclosures and power supply hookups, and of course getting the drives to work at all. github.com/bkw777/FluxEngine_Kit
- self_awareness 2y agoA must-have companion tool: https://github.com/jfdelnero/HxCFloppyEmulator https://github.com/jfdelnero/HxCFloppyEmulator I've learned about Greaseweazle in some previous thread here on HN, bought it, and had a really good time browsing through some of my old Amiga floppy collection. It works really well.
