Apple Macintosh Perfoma 600 Series - Manual

Macintosh User’s Guide Update:
The Utilities Floppy Disk and Using Internal HD Format
Your Macintosh Performa user’s guide refers to the Utilities floppy disk. If
your computer came with a CD-ROM drive, you may have either a Utilities
floppy disk or a Macintosh Performa CD. If you do not have a Utilities disk,
you can find the same programs on the Macintosh Performa CD.
This update describes how to use Internal HD Format, a program that is
either on your Utilities disk or your Macintosh Performa CD. You should locate
this program and make a note of where it is, in case you need it someday.
IMPORTANT Chapter 11 in your Macintosh Performa user’s guide tells how to
initialize a hard disk using the Apple HD SC Setup program. Your computer
has an internal IDE hard disk rather than an internal SCSI hard disk. Follow
the instructions in your Macintosh Performa user’s guide only if you want to
initialize or reinitialize an external Apple SCSI hard disk. Follow the
instructions in this update if you ever need to reinitialize your computer’s
internal hard disk.
Checking for damage on the disk
You can use the Internal HD Format program at any time to check for
damaged blocks (segments of the hard disk that cannot reliably be used to
store information). To do this, choose Scan All Blocks in the Functions menu.
(When the program finds damaged blocks, it marks them so the computer
will know not to store information in them. This process does not harm any
data on the hard disk.)
