1.44MB was the effective capacity of floppies until they died out. There was stuff like VGACopy that could format them with higher capacity (since floppy controller access was fairly low level), but it was an uncommon thing among tinkerers, the disks themselves were not marketed for more than 1.44MB, and I doubt they were tested above their nominal capacity (and even at that they were not exactly known as super reliably).

What a marvel of engineering. All I got is plastic boxes. Thinking about it I'm not sure if having the next paragraph written by a different person is actually a good idea. Organizing your notes into a book undisturbed by better men is sure to impress a lot more. I would hope the final draft of my book about antique hardware wouldn't quote someone who remembers the bad parts better than the good.
