Writing to Physical Disks

COMMAND LINE · DD

Use the dd utility to write the raw image byte-for-byte to your floppy device. Identify your device node first — typically /dev/fd0 on Linux.

dd if=diskname.img of=/dev/fd0 bs=512

SPECIALIST HARDWARE · FLUX-LEVEL

For sector-perfect writes with full flux-level fidelity, use a Greaseweazle board. Recommended for all formats, especially 360KB and ED disks.

gw write --drive A diskname.img

GUI TOOL · RAWWRITEWIN

RawWriteWin is the classic Windows tool for raw floppy image writing. Balena Etcher also works for standard-geometry images on USB-attached drives.

rawwritewin.exe → select image → write

EMULATION · QEMU / DOSBOX

Disk images can be used directly in emulators without writing to physical media. Mount as drive A: and boot as normal.

qemu -fda diskname.img -boot a
