When I was selling my software on diskette, I wrote my own tools for diskette
duplication, using a Victory autoloader - I also boiled-down the core functions
into a one-at-a-time disk command line duplicator that works with standard
floppy drives called XDISK.
Like most disk-to-file copiers it will read a complete image of the floppy
track by track into a disk file - unlike most file-to-disk copiers, it
will low-level format, write, and verify each track in a single pass as it
writes the file back to a disk. It does not care *WHAT* is previously on the
disk, as the first command it issues on each track is "format track".
This can be used to restore disks that DOS refuses to format due to problems
in track-0 (just write out a blank floppy image) - I can send it to you if
you like (runs under any version of DOS).
Regards,
Dave
