Your Macintosh can’t read a floppy disk.
If you see a message that a floppy disk is unreadable, try one of the following:
mIf the disk has never been used, you may simply need to initialize it.For
instructions, see the “Disks” topic of Macintosh Guide, available in the
Guide (h) menu.
mThe disk may be damaged. See “Repairing a Damaged Disk” later in this
chapter for information on testing and repairing disks.
If you are trying to use a DOS disk, consider the following:
mThe disk may have been formatted incorrectly on a DOS computer. On
DOS computers it’s possible to format a standard double-sided disk in a
high-density (1440K) format, and vice versa. Disks formatted in this way
cannot be read by a Macintosh computer.
When formatting disks on a DOS computer, always format standard
double-sided disks in the 720K format. Always format high-density disks
in the 1440K format.
If a disk has been formatted incorrectly, use a DOS computer to copy its
contents onto another disk that has been properly formatted.
