DiskDup is a shareware utility that creates, mounts, and writes disks and disk images of floppy disks and other media. Unlike ShrinkWrap, DiskDup can create images of 400K MFS disks. It can overcome mild forms of copy protection, and can also be set to tolerate bad sectors in the case of damaged media.

DiskDup is available as either the shareware Plus ("+") release, or its commercial Pro variant, though confusingly, the version numbers of each do not correspond with one another. For clarity's sake, the downloads here are listed in their approximate release order, with the Pro version listed following it's corresponding Plus release, when available.

The principle distinction between the Plus and the Pro versions is the added ability in Pro to duplicate any size removable cartridge (Zip, Syquest, Bernoulli, etc.), in addition to floppy disks. The last available releases of DiskDup are DiskDup+ 2.9.2a and DiskDup Pro 1.3.2a. If in doubt, use one of these.

List of available versions:

DiskDup+ 1.5.4, as found at www.nic.funet.fi
DiskDup+ 1.6, as found on MacRepo (originally bundled with La Cie's Silverlining)
DiskDup+ 2.1, as found on MacGUI
DiskDup+ 2.5.1, as found on MacRepo
DiskDup+ 2.6a, as found on VintageAppleMac.
DiskDup+ 2.7 (compressed using StuffIt 3.6)
DiskDup+ 2.7.1, as found on MacGUI
DiskDup Pro 1.0.3, as found on Grenier du Mac (repackaged as a binhexed StuffIt file)
DiskDup+ 2.8.2, as found on VintageAppleMac.
DiskDup Pro 1.2 (pre-registered)
DiskDup+ 2.9.1, as found on VintageAppleMac. (2.9.0 was the first version with HFS+ compatibility.)
DiskDup+ 2.9.2 (April 1999) - Provided as an emulator-ready disk image
DiskDup+ 2.9.2a (September 1999 - as found on Roger Bates' website, via Internet Archive)
DiskDup Pro 1.3.2a (pre-registered)

DD Pro 1.3.2a needs more than 4 MB of memory, as i just found out on my SE/FDHD.

Hi zoinknoise. I'm not sure why that could be happening for you as it loads in as little as 600k for me, which is what it is set to, after extracting it from the .sit archive.

heads up: DD Pro 1.3.2a needs more than 4 MB of memory, as i just found out on my SE/FDHD.

I had found several, and so just was trying to get as many up as I could find or knew about.

DiskDup v. 2.2.1 is on World of Mac and The Ultimate Macintosh Collection in Utilities. I have not looked at them to check that they are what you want (There is no + in the folder names).

Also I can point you at other old versions if you are trying to get them all.

by lilliputian - 2020, September 10 - 10:50pm

Nice! Thank you!

by Franky233 - 2020, September 10 - 5:53pm

I've seen that you looked for v2.22 here. I've not found it yet, but I've found and uploaded v2.1 instead. This was on MacGui. I let you manage the description of the page.

by lilliputian - 2020, September 3 - 3:20am

very nice! Will you be adding it to this page?

EDIT: Added v1.0.3 from Grenier du Mac!

by Realitystorm - 2020, April 12 - 9:21pm

I've managed to track down a registered copy of DiskDupPro 1.0.3 hidden on the web.
It works under system 6.0.8 so I'll be adding it to my image files for people starting out with SCSI2SD or FloppyEMU etc.

So when you say this can replace disk copy, do you mean I can delete disk copy to save hdd space? Also how does this compare to ShrinkWrap?

by jdmoser - 2015, February 8 - 7:21am

This is perfect for creating and writing images for your 400k and 800k floppy Macs... even more so on a newer OS 9 machine with an internet connection and a floppy drive, like the Power Macintosh G3. Totally invaluable.

A little known tid-bit (perhaps): This has to be the only disk imaging software I know of that can mount Disk Copy 4.2 (and its own DiskDup+) floppy disk image files onto a System 6 desktop, like Disk Copy 6 & ShrinkWrap can in Systems 7x - 9x. - Gets 5 stars from me for that, alone.

[Edit]: exception - "MountImage" can also mount Disk Copy 4.2 image files onto a SSW 6.x desktop.

by Balrog - 2010, September 30 - 9:16pm

Please add v1.3.2a to this page anyway.

by Balrog - 2010, September 30 - 9:14pm

The one and only utility that can overcome copy protection is Copy ][ Mac. But it can't create images, only duplicate disks. If anyone wants it I can upload it (I have most of the versions).

Edited by IIGS_User: Copy ][ Mac link added

by bertyboy - 2010, September 30 - 7:51pm

I've found a copy of DiskDup Pro v1.3.2a. do you think it has more features than this one ? Hoping it can overcome some of the copy-protection used with bad sectors on floppies.

I'll check it out in vMac and give it a check with Disinfectant, if it's not the same as this one, I'll add it to the page.

by xy - 2010, September 23 - 10:15am

Yeah, but DiskCopy 4.2 does not work on Mac OS 9.2.2. DiskDup does.

by Balrog - 2010, September 22 - 9:17pm

Better to use Disk Copy 4.2.

by Attila - 2009, December 22 - 6:02pm

I've added an AutoTyper to the archive, so that DiskDup+ images that have lost their file type and creator information can be opened by DiskDup+ again. For some reason it won't give you the option of opening them even though they're still good. Now, just drag and drop onto the AutoTyper and everything's A-OK!
