Checking for damage on your internal hard disk

You can check for damage on your internal hard disk with the Internal HD Format program, which is on the floppy disk labeled Disk Tools that came with your computer. If your computer came with a CD-ROM drive and you didn’t receive floppy disks, you can find Internal HD Format on the CD-ROM disc that contains system software.You can use Internal HD Format at any time to check for damaged blocks (segments of the hard disk that cannot reliably be used to store information).

1Start up your computer from the Disk Tools disk or the CD-ROM disc that contains system software.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy Disk” in the section “Initializing a Hard Disk” earlier in this chapter.

2Open the Internal HD Format icon.

You may need to look in a folder called Utilities to find Internal HD Format.

3Choose Scan All Blocks from the Functions menu.

If the program finds damaged blocks, it marks them so the computer will not store information in them. This process does not harm any information on the hard disk.

Testing an external SCSI hard disk

You can test an external Apple SCSI hard disk with the Apple HD SC Setup program, which is on the floppy disk labeled Disk Tools that came with your computer. If your computer has a built-in CD-ROM drive, and you didn’t receive floppy disks, you can find the Apple HD SC Setup program on the CD-ROM disc that contains system software.

1Start up your computer from the Disk Tools disk or the CD-ROM disc that contains system software.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy Disk” in the section “Initializing a Hard Disk” earlier in this chapter.
