Disk Copy 4.2 images, typically of floppy disks.There are several types of disk images you’ll come across working with 68k systems: This guide is written for Disk Duplicator (DD) is a standard application that can be used for imaging hard drives, removable drives, memory cards, usb keys, and CD ROMs.ĭisk images are essentially binary (bit for bit) copies of the contents of a storage device or medium such as your Hard Drive, removable drive, memory card or CD-ROM (ISO files). With SCSI being essentially obsolete, and the fact that Macintosh systems (since OS X 10.6 I think) can no longer write to HFS formatted disks, the best way to use modern systems when setting up your classic 68k system is to create a bootable drive image using a Macintosh 68k or PowerPC emulator then writing that disk image to a real or emulated disk drive.
