For retrofit purposes, it's probably attainable to use solid state (no moving parts) floppy disk emulators that use USB thumb drives or CF/SD cards instead of error-prone, real floppy disks. Every time a floppy drive moves over a sector to read or write, it wears that area mechanically. Magnetically, bits just seem to rot from floppy disks randomly with time more likely failure mode for previously good floppies.
Let me complain you about how error-prone and unreliable are real floppy disks. ):
