Making Floppies

Software is stuffed and requires an expander, such as StuffIt Expander (which was traditionally bundled with early Mac web browsers). Mounting disk images or making floppies from them requires Disk Copy (download Disk Copy) or MountImage.

You will need a 400K or 800K floppy drive to produce single-sided disks for use with the Mac 128K and 512K Fat Mac. Apple’s high density floppy drives cannot format single-sided floppies.

You cannot use a USB floppy drive to create 800K floppy disks; they can only be formatted and written to using an Apple 800K or 1.4M HD floppy drive.

You should have no trouble formatting and writing to high density floppies using a USB floppy drive.

Drive Prep

Whenever possible, Apple branded hard drives should be formatted or updated with HD SC Setup 7.3.5 or later before installing a new version of the OS. (Exception: If the hard drive of a Mac Portable is formatted with any version newer than 7.3.1, it will crash instead of waking from sleep mode.)
