Apple Macintosh LC 630 DOS - Manual (Page 95)

m If the hard disk is your startup disk, start your computer using the
Disk Tools floppy disk or (if you have a built-in CD-ROM drive) with the
CD-ROM disc that contains system software. (For instructions on how to
start up your computer from the CD-ROM disc, see “Starting Up From
a CD-ROM Disc” in the section “Initializing a Hard Disk” later in this
chapter.) Then follow the instructions in “Repairing a Damaged Disk”
later in this chapter to test your startup hard disk and repair any damage.
If repairing the disk doesn’t help, follow the instructions in “Installing or
Reinstalling Mac OS System Software” later in this chapter to reinstall
system software on your startup hard disk.
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 disks. For instructions, see “Rebuild
Your Desktop Regularly” in the section “When You Run Into Trouble” earlier
in this chapter.
If icons do not appear correctly after you rebuild the desktop, restart your
computer while pressing the Shift key to temporarily turn off system
extensions. When you see the “Welcome to Macintosh—extensions off”
message, release the Shift key and press the Option and x keys until you see
a message asking if you want to rebuild the desktop.
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 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.
m The disk may be a DOS disk that the Macintosh environment cannot use.
Try switching to the PC environment and inserting the disk again.
