Chapter 3 - BIOS Setup Program
3.3.7.1 Using the Bad Track Table
Bad tracks are areas of the fixed disk that cannot properly store data. Bad tracks are displayed in the
center of the menu. This list is automatically updated when the
<
F5 >,
<
F6 >, or
<
F8 > commands
are used.
To add a bad track manually, press < Insert> and use the arrow keys or < Enter> to select the cylinder
and head fields. Enter the appropriate information and press <FlO> or <Enter>. You are alerted if
you enter an invalid head or cylinder. Use the arrow keys to position the cursor, press < Delete>, and
then enter the new information.
Press < F2 > to clear the entire bad track table. Press < F3 > to print the table. If the drive has already
been formatted, press < F5 > to search for existing bad tracks.
3.3.7.2 Setting the Interleave
The interleave is the value used by the format operation to interleave the fixed disk tracks. Press < F4 >
to set the interleave. Consult your disk drive manual to set the proper interleave.
NOTE
The interleave specified is the value which will be used to format, which
is not necessarily the current value for your fixed disk.
If the interleave is not set, a default of three is used.
3.3.7.3 Analyzing the Fixed Disk Surface
If you do not need to reformat the entire fixed disk, but want to perform a thorough media test to detect
any bad or marginal areas, select
<
F6 > to analyze the surface.
CAUTION
Analyzing the surface causes all data on the disk to be lost.
Any bad tracks found in the analysis are automatically added to the bad track table. As they are located,
the bad tracks are reformatted as bad to prevent these areas from being used subsequently.
