Select this choice to perform a low-level format on a hard disk drive. Depending
on the hard disk drive capacity, the Low-Level Format program could take up to
two hours.
Use the Low-Level Format program:
— When you are installing software that requires a low-level format
— When you get recurring messages from the diagnostic tests directing you to
run the Low-Level Format program on the hard disk drive
— As a last resort before replacing a failing hard disk drive
Note: If your server has a PCI RAID adapter installed, refer to the RAID adapter
documentation for instructions for performing low-level formats on hard
disk drives attached to the adapter.
To start the Low-Level Format program:
1. If the hard disk is working, make a backup copy of all the files and programs
on the hard disk drive. (See your operating system information for
instructions.)
2. Select
Format Disk
; then, follow the instructions on the screen.
Note: Hard disks normally contain more tracks than their stated capacity (to
allow for defective tracks). A message appears on the screen if the
defect limit is reached. If this happens, have the system serviced.
