Performing a low-level disk format:
You can
perform a low-level format on hard disk drives using the
Format Disk feature of the SCSISelect Utility program.
Depending on the hard disk capacity, the low-level format
program could take up to two hours.
When to use the format disk program:
Use the
Format Disk program:
Ÿ
When you are installing software that requires a
low-level format
Ÿ
When you get recurring messages from the diagnostic
tests directing you to run the Low-Level Format
program on the hard disk
Ÿ
As a last resort before replacing a failing hard disk
drive.
Note
For information about backing up all of the files, see
the operating-system documentation.
Starting the low-level format
Attention
The low-level format erases all data and programs.
1. If the hard disk drive 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 disk drives 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, refer to the ServerGuide
information in the “ServerGuide and Netfinity Manager
Information” section of this
Server Library that comes
with the server.
Verifying the disk media:
Select Verify Disk Media
to scan the selected hard disk drive for media defects,
such as bad tracks. All recoverable defects will be
remapped.
The Verify Disk Media program takes about 15 to 20
minutes to complete.
