SAMdisk is a command-line disk image utility for Windows 2000 or later.
Read and write almost any soft-sectored floppy disk format compatible with the PC floppy controller, including some traditionally copy-protected formats. Also supports hard disk imaging to and from HDF and raw formats.
Low-level floppy device access requires the fdrawcmd.sys driver to be installed.
