Apple Power Macintosh 5400 series - Manual (Page 86)

Icons do not appear correctly on your screen.
You need to rebuild the desktop—a process that helps your Macintosh keep
track of files and folders on your hard disk. For instructions, see “Rebuild
Your Desktop” in the section “When You Run Into Trouble” earlier in this
chapter.
If icons do not appear correctly after you rebuild the desktop, try rebuilding a
second time.
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 area of Macintosh Guide, available in the
Guide (h) menu.
m The disk may be damaged. See “Testing and Repairing a Damaged Disk”
later in this chapter for information on testing and repairing disks.
If you are trying unsuccessfully to use a floppy disk created in a PC (personal
computer), DOS (Disk Operating System), or Windows environment, consider
the following:
m When formatting floppy disks on a DOS computer for use in a Macintosh,
you 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.
