Starting the Low-Level Format Program Attention The low-level format program erases all data and programs. Note If the server has a RAID adapter installed, refer to the RAID adapter documentation for instructions for performing a low-level format on a hard disk drive attached to the PCI RAID adapter. 1. If the hard disk is working, make a backup copy of all the files and programs on the hard disk drive 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, replace the drive. 3. To install an operating system after the hard disk drive is formatted, follow the instructions in the "Software and Netfinity Manager Reference" section of this Server Library. Verify Disk Media: The verify disk media utility scans the drive for defective sectors. All recoverable information found on defective sectors is remapped to alternate sectors. This utility also indicates if the drive is defective. Use this utility if you suspect bad sectors on a disk drive. Netfinity 7000-M10 - Type 8680 41

Starting the Low-Level Format Program
Attention
The low-level format program erases
all
data and
programs.
Note
If the server has a RAID adapter installed, refer to the
RAID adapter documentation for instructions for
performing a low-level format on a hard disk drive
attached to the PCI RAID adapter.
1.
If the hard disk is working, make a backup copy of all
the files and programs on the hard disk drive
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, replace
the drive.
3.
To install an operating system after the hard disk
drive is formatted, follow the instructions in the
“Software and Netfinity Manager Reference” section
of this
Server Library
.
Verify Disk Media:
The verify disk media utility
scans the drive for defective sectors.
All recoverable
information found on defective sectors is remapped to
alternate sectors.
This utility also indicates if the drive is
defective.
Use this utility if you suspect bad sectors on a
disk drive.
