SAMdisk v3 by Simon Owen is out, it's a command-line disk image utility for Windows 2000 or later. The utility supports transfers between floppy disks and disk images (DSK/MGT/IMG/HDF), and is designed to work with almost any soft-sectored disk format compatible with the PC floppy controller, including some copy-protected formats. Low-level floppy device access requires the fdrawcmd.sys driver to be installed.
You can use a java GUI written by DevilMarkus : SAMdisk GUI.
This utility requires a floppy drive connected to a standard motherboard connector. USB floppy drives cannot be supported as there is no way to access their embedded floppy controller chip.
