How do I format a floppy disk with ProDOS?
Copy a 720KB or 1.4MB ProDOS disk image to a PC-formatted floppy disk with “Volume Copier” in the Tools menu. If you don’t have a disk image handy, create one with File->New->Disk Image. CiderPress does not perform low-level disk formatting, e.g. reformatting an 800K disk for 720K. From Windows, open My Computer, right-click on the floppy drive, and select “Format”.
