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 controls may be changed at any time.
Here is a list of the principal features of DiskDup+:
• Performs sector duplication of either 400K, 720K, 800K, or 1440K floppies.
Unused sectors may be skipped for faster duplication.
• Automatically creates disk Labels for each of the disks duplicated.
• You can copy 800K Masters onto 1440K copies (with increased free space)
• Disk images may be Read/Written from a hard drive.
• Disk images may be mounted from the Finder for direct access to the file contents.
You may also cuplicate or mount file images for Apple's DiskCopy program.
• 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.
• Tolerates bad sectors if they do not involve actual disk data.
• Option to copy a Master with bad sectors - use in able to perform file recovery on a copy.
• Controls for easy use with "Jukebox Five" automatic disk feeder.
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. If you find yourself using the program for more than simple evaluation of its capabilities, you are requested to register as a user of the program. You may either send a $25 check or money order to this author, or call in and charge it on VISA or MasterCard. You will receive back a disk with the latest version of the program, a manual on the use of DiskDup+, access to the "mount image" feature, and instructions for avoiding the ShareWare dialog that is displayed during program execution.
