Fixed Disk Utilities
Note: The Format Fixed-Disk utility erases all data on the fixed
disk and reformats the fixed disk. Before using this utility, backup
all data on the fixed disk being formatted.
Use the Format Fixed-Disk utility only when intermittent read or
write errors have occurred on the fixed disk or the diagnostic
programs instruct you to use this utility. The Format Fixed-Disk
utility formats the fixed disk and writes new addresses on it.

The Diagnostics Diskette Copy Utility provides a program to copy
the diagnostics diskettes. The utility provides the following:
• A message when the
source diskette is needed
• A message when the
target diskette is needed
•
A warning message to tell the system operator that the data on
the target diskette will be destroyed
• Formatting of the target diskette
• Copying of the data from the source diskette to the formatted
target diskette.
You may have to change the source and target diskettes during the
copying procedure. A message displays to inform you when to
change the diskettes.
