Disk Copy was the default utility for handlinglogical volume images inSystem 7 throughMac OS X 10.2 (usable inSystem Software 6 as well). In later versions ofmacOS it has been replaced byDiskImageMounter for mounting the images andDisk Utility for creating them.
"Disk Copy 4.2" (DC42) is the common name used to refer todisk images offloppy disks created by the 4.2 version of Disk Copy.[1][2][3] DART is a variant that supports compression, and was initially handled by the DART (Disk Archive/Retrieval Tool) utility.[4]
Disk Copy 6.0 added support for theNew Disk Image Format (NDIF).[1][5] Versions of Disk Copy inMac OS X added support for the newerUniversal Disk Format (UDIF) image format, introduced with DMG files in Mac OS X.
Although the last official public release of Disk Copy forMac OS 9 was version 6.3.3, there was to be a version 6.5 that supported OS X's UDIF image format. But because Apple had stopped support for OS 9 already, support for the old OS was eventually removed in favor of Mac OS X. As such the OS 9 version of 6.5 only ever made it to beta 13 before development on it stopped. There was also a developer version 6.4 that 6.5 was based on and had most of the same functionality, but as a developer version it was never released. Although version 6.4 and 6.5 will read DMG images when the system is booted into OS 9, they can only do so if the image is not compressed.
Other image formats supported by Disk Copy include DiskSet andraw disk images.
Disk Copy was also the name of anApple utility distributed with some of the earliest versions of theclassic Mac OS. In order to copy 400Kfloppy disks using as few disk swaps as possible on a machine with only 128K ofRAM, the original Disk Copy used thescreen buffer to store binary data from the disk being copied; as a result, the screen (other than a small area at the bottom displaying theGUI) filled with noise while copying was in progress. It was shipped with System 1.1 and System 2.0.
