Your Macintosh can’t read a floppy disk.
If you see a message that a floppy disk is unreadable, try one of the following:
m If 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.
m The disk may be damaged. See “Repairing a Damaged Disk” later in this
chapter for information on testing and repairing disks.
If you are trying unsuccessfully to use a DOS floppy disk, consider the
following:
m When formatting floppy disks on a DOS computer for use in a Macintosh,
users need to format standard double-sided disks as 720K disks and high-
density disks as 1440K disks. Because DOS computers allow standard
double-sided disks to be formatted in 1440K format and high-density disks
to be formatted in 720K format, it’s possible that your disk has been given
a format that won’t work in a Macintosh.
If you think your DOS floppy disk might have a format that doesn’t work
in a Macintosh, use a DOS computer to copy the contents of your DOS
floppy disk onto another DOS floppy disk that has been properly formatted
for use in a Macintosh.
The pointer (

) freezes on the screen.
Your system has a software problem.
m Press x-Option-Esc to quit the application program in use when the
problem occurred. If this works, you can save the documents open in other
programs before restarting.
m Restart your Macintosh. (For instructions, see “Start Over” in the section
“When You Run Into Trouble” earlier in this chapter.) Most software
problems are temporary, and restarting usually corrects the problem.
