SUMMARY
When attempting to format a 3.5-inch high density (1.44 MB) floppy disk as a low density (720K) disk, the following error message may be displayed:
This is due to the ability of some floppy drives to sense the media type of 3.5-inch disks. High density 3.5-inch disks have two holes in the disk shell. Low density 3.5-inch disks have only the write- protected hole. The disk will format correctly as a 1.44 MB disk.
MORE INFORMATION
To make a floppy drive recognize a high density disk as a low density disk, cover the second hole (not the write-protected hole) in the disk shell.
