Thank you for your interest in the DiskDup+ program. This program has been written to automate as much as possible the sector by sector duplication of a floppy onto one or more duplicates. All controls of the program are displayed by the one control dialog which is always presented by the program. These controlls may be changed at any time.
Here is a list of the principal features of DiskDup+:
¥ Performs sector duplication of either 400K, 800K, or 1440K floppies.
¥ Formats copies as single or double sided as necessary to match the master disk.
¥ Optionally performs a complete read back of the copy to verify all data against the original in order to assure full data integrity.
¥ Requires only a single floppy disk drive (either internal or external). If you have two drives, you may alternate between them for maximum efficiency.
¥ A new master may be read in at any time without exiting the program.
¥ A Copy counter displays the number of duplications completed.
¥ The entire disk data is held within the Mac if it has sufficient memory. With less memory, two passes may be required to complete the operation.
¥ An optional warning tells you if you are about to write onto a formatted disk.
¥ Master disk is never mounted, so viruses can never propogate ONTO the master (and its copies) during the duplication process.
¥ Duplicates Macintosh MFS, Macintosh HFS, Apple A/UX, and any other readable diskette.
The program has been written to work best with 1 megabyte (or more) of internal memory for 400K and 800K floppies, or 2 megabyte for 1440 floppies. It will still function when less memory is available. In this case, it will require 2 passes over each disk. In two pass mode, the first half of the master is read into memory, and you may then write the first half of as many copies as desired. You then re-insert the master in order to read in the second half for writing on all your copies. In this mode, the copy counter of DiskDup+ will properly inform you of where you are in the process. If DiskDup+ indicates that it does not have sufficient memory, check to see whether you are using either the Ram CACHE (see control pannel), or an internal RAMdisk. Both of these features tie up large amounts of internal Mac memory.
This is a ShareWare program. As such you are free to use/copy, and pass on copies to your friends and neighbors.
