Repairing a damaged disk

Disks can become damaged by repeated use and handling.

When do you need to repair a disk?

If you see a message reporting that a disk is damaged or unreadable, you may need to repair the disk.

Try these suggestions first

If you can’t start up from a hard disk or you don’t see the hard disk icon on the desktop, try the following:

mIf the hard disk is internal, shut down your Macintosh, wait at least 10 seconds, and then turn it on again.

mIf the hard disk is external, make sure that it is turned on and that its cable is connected firmly; then restart the Macintosh.

mIf the hard disk is your startup disk, start up with a different startup disk. If the hard disk’s icon appears on your desktop, reinstall system software on the hard disk (see “Installing or Reinstalling System Software” later in this chapter).

mCheck the ID numbers of all SCSI equipment connected to your computer. Each device must have a unique ID number (the computer itself has the ID number 7, and the internal hard disk has the number 0). Also check that the chain of devices is terminated properly. For information on setting SCSI ID numbers and terminating a SCSI chain, see the manuals that came with your SCSI equipment.

mTest the disk following the instructions that come next.
