This means you need edge-triggered logic to read them, regular GPIO reads will often miss the pulse. – Signals from the floppy drive are short pulses, not neatly timed high and low signals. This write-up seriously undersells the difficulty of getting a floppy drive to work on a plain Arduino: I’ve been able to recover more than 99% of the data from really dirty, crusty, mold infested disks.

The windows application is still a bit buggy but if you’re interested here’s the github link, all the files including the stl files for the cleaning kit can be found here:Īll in all it renewed my appreciation for the storage standard. It was interesting to see what a bad sector looks like. There’s also an option (for really advanced users) to connect the Rigol DS1054z directly to the flux amplifier of some disk drives that has that signal available to tap into the analog flux signal to see if you can recover more data that way. I’ve also developed a 3D printed cleaning kit that can be used to hold the door open and a turn tool to rotate the disk donut. The main purpose was recovering as much data as possible, not so much as direct file access though. Mine was entirely controlled by a Windows application and the arduino passed the flux data on through its high speed usb port. With microstepping the disks can still be recovered. I did something similar with an Arduino Due, with a step stick to control the stepper motor for disks that had the donut come loose from the metal hub (3.5″ disks).

We can see that it will be extremely useful to anyone working with retrocomputer software who is trying to retrieve old disks, and we look forward to seeing it incorporated in some retrocomputer projects.

The pictures show a 3.5″ drive, but it also supports 5.25″ units and both DD and HD drives. In addition it incorporates the FatFS library for MS-DOS FAT file-level access, and finally the ArduDOS environment which allows browsing of files on a floppy. The library provides functions to allow low level work with floppy disks, to read them sector by sector. shows us this in style, with a floppy interface, software library, and even a rudimentary DOS, for the humble Arduino Uno. The interface for a floppy drive might have required some complexity back in the days of 8-bit microcomputers, but even for today’s less accomplished microcontrollers it’s a surprisingly straightforward hardware prospect. For many of us the passing of the floppy disk is unlamented, but there remains a corps of experimenters for whom the classic removable storage format still holds some fascination.
