Disk Copy 6 is a complete rewrite of Apple's earlier disk duplication
software [Disk Copy 4.2][1], which it obsoleted. It bears little
resemblance to its earlier namesake other than it can mount and write
to Disk Copy 4.2 format as an option if required. Disk Copy 6 now
supported copying, creating, converting, and mounting Disk Copy 4.2
and NDIF disk images, adding support for AppleScript, log files,
CRC-32 checksums, DiskScripts, and digital signatures. It is a very
useful program for mounting disk and CD images in classic Mac OS
environments. It works with .IMA, .IMG files, and others, and runs
under Mac OS 7.0.1 to Mac OS 9.2.2.

 1. DL #1: Disk Copy 6.1.2; A milestone release for Disk Copy 6.x - New features include mounting images directly from an AppleShare 5.0 server, over an AppleTalk or TCP/IP connection. The Mount Image and Convert Image commands now include a "Skip" button during checksum verification. If Disk Copy 6.1.2 is in the foreground and a disk (floppy, CD, etc.) is inserted, the Create Image from Disk command will automatically start. Plus improved support for the Macintosh Application Environment. Updated April 3, 1997.

 2. DL #2: Disk Copy 6.1.3; Fixed an issue making floppies from uninitialized disks on certain machines, fixed an issue when converting certain Disk Copy 4.2 format disk images, made various interface improvements, and added two-byte character support for Apple Language Kits. Disk Copy 6.1.3 will launch without the presence of the AppleScriptLib shared library, but the attachable Scripts menu will be disabled.

 3. DL #3: Disk Copy 6.2; Milestone release. Adds ability to create blank read-write images. Support for Macintosh Extended format volumes. Adds support for segmented images.

 4. DL #4: Disk Copy 6.3; Another milestone release. Introduces support for creating self-mounting images. Various improvements to AppleScript support. Fixed possible data loss issue when imaging a folder from an HFS+ volume. Imaging a folder with less than 32MB of data from an HFS+ volume results in an HFS formatted volume. Updated July 1, 1998.

 5. DL #5: Disk Copy 6.3.1; Bug fixes: An issue that prevented making a read-only or read-only compressed image from volumes that have data at the end of the volume has been corrected. Updated August 27, 1998.

![Note][2] | Note: Disk Copy 6.3.1 is the final version of the Disk
Copy 6 series which can access external USB floppy drives for writing
(on Mac hardware without internal floppy disk drives), where the "Make
a Floppy" menu is not greyed out.
---|---

 6. DL #6: Disk Copy 6.3.2; Bug fixes: An issue that prevented accessing AppleShare file servers via Navigation Services dialogs has been corrected. Various interface improvements. Updated October 03, 1998.

 7. DL #7: Disk Copy 6.3.3; This was the final officially supported, publicly released version of Disk Copy for the classic Mac OS 9. - Adds support for accessing disk images with the Macintosh Compatibility Application of Mac OS X Server. Updated January 04, 1999.

 8. DL #8: Disk Copy 6.4; This was an Apple internal release only. This version is able to mount and edit .dmg archives (unencrypted, uncompressed read/write images, only). ? Requires a PPC Mac OS 8.5.1 or newer.

 9. DL #9's and #10: Disk Copy 6.5b11 and b13; These are two non-released beta versions of Disk Copy 6.5.
These can access some uncompressed .dmg and .cdr formats. ? Both
require a PPC Mac OS 9.1 or newer.

 10. DL #11: Disk Copy 6.3 Scripts; These add extra features to Disk Copy 6, such as disk image splitting of large Disk Copy image files into smaller chunks enabling disk spanning. Creating self mounting images (double click to mount disk images that don't require the presence of Disk Copy 6 itself). They are provided as working examples of how to use AppleScript to control Disk Copy.

 11. DL #12: Disk Copy Command Module Plugins; CM plugins to enable right-click (or Option-click for one-button mouse users) mount disk images from a contextual menu. It will optionally verify the checksum of the image. It does not require the Disk Copy application to be present. It requires a Mac OS 8.1 or newer.

 12. DL #13: Disk Copy 6.1 GM; earliest 2nd-gen version, 6.1 gold master, from the Apple Developer Connection CD, April 1997. Includes Quick Reference (text) and User Guide (pdf).

 13. DL #14: Create SMI 1.0; an Apple Script to create SMI(Self Mounting Images). Requires 8.1, though the resulting smi image will work on 7.0.1 and up. By Ben Lukens.


 14. Manual DL: Disk Copy 6.1.2 User's Guide (PDF). This User's Guide was included with the Disk Copy 6.1.2 release. It is still relevant for later versions of Disk Copy, up to and including Disk Copy 6.3.3.

Compatibility
Architecture: 68k PPC

Some features are not available for earlier versions of the Mac OS.
For example; creating Self Mounting Images (.smi) requires Disk Copy
6.3 and later & Mac OS 8.1 or later. However ".smi" images created by
Disk Copy 6.3x can self-mount on Mac OS systems from System Software
7.0.1 to Mac OS 9.2.2 and without a copy of Disk Copy 6 being
installed on that system.

Note: All versions of the Disk Copy 6 series up to and including
version 6.3.3 are FAT encoded (both 68k & PPC native), and can be used
by Macintoshes that are capable of running Mac OS's from 7.0.1 to
9.2.2.
? The unofficial 6.4 internal release requires a PPC Mac and Mac OS
8.5.1 or newer
? The 6.5x betas are PPC only, requiring Mac OS 9.1 or newer (and are
incompatible with SheepShaver).
