> If using Win10 or 11, you may find that even with a zeroed floppy or HDD partition when you power off, the partition will be silently formatted just as Windows last remembers it when you reboot, transparently without notice.

Tell us more about that

I have a USB floppy drive with a known good disk in it. Not sure if a regular 34-pin floppy would be any different. But blanked it, connected to Win 11, and rebooted. The drive seeked on startup, but otherwise it's still blank:

    dd if=/dev/rsd1c | hexdump -C
    00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
