Kind of sucks that my Commodore 1541 floppy drive (5.25" floppies) is giving me read/write errors, and I have no idea where I put my head cleaner floppy long ago. (Have to rely on SD2IEC on my Commodore 64, and it’s not compatible with some turbo loaders or other programs that do weird drive magic.) And, of course, while I might run into head cleaner tapes on specialty shops, good luck running into 5.25" cleaner floppies these days.
