Off topic but it's funny to me how seemingly everyone in this writes "floppy disk" correctly with a "k" but writes "discs" (when still talking about the floppy disks) incorrectly with a "c". Must be a habit when not adding floppy in front!

It is funny. I looked it up and apparently the spelling of the general work "disc" (meaning, thin circular thing) is disc in British and disk in American. But universally it's disk for floppy disks and hard disks and disc for compact discs, DVDs etc. My theory is "disc" looks a bit more "modern" for some reason, hence using it for the newer media. For me (a British speaker), it seems totally natural to use "disk" for floppies and hard disks, but disc otherwise.

When I looked it up, "disc" meant the recording medium itself without any casing or I/O mechanism. Anything else was a "disk".
