To add a bad track, follow these steps:
Press
A.
You see this prompt:
Enter cylinder number (1 - xxxx):
Type the number of the cylinder containing the missing bad track, and
press
Enter.
You see this prompt:
Enter head number
- yy):
Type the head number for the bad track, and press
Enter.
The maxi-
mum valid cylinder and head numbers (
XXXX
and yy) vary according to
the type of the hard disk.
To cancel this operation, press
Enter
without entering a value. You see
this message:
Table unchanged.
If you enter an invalid cylinder or head number, a reminder of the range
of values is displayed, and the program asks you to enter the value again.
When you complete a valid entry, it appears in the table, and you can select
another command.
If you make a mistake, move the cursor block to the incorrect track, and
press C to alter the track data. Or you can press
D
to remove the track from
the table. Change the track data just like you add a track.
When you have finished editing,
check the entries in the table once
more. When you are sure the table is correct, press
F.
The program displays a warning about the consequences of proceeding
with formatting, and the remaining steps are exactly the same as for a normal
conditional format.
Destructive Surface Analysis
Use this option to accurately locate any bad tracks on a hard disk, and
to flag any bad tracks that are not flagged.
WARNING: If any errors occur during this check, all data on the track
that produces the error is destroyed. For this reason, if
you think that an unflagged bad track is causing trouble,
first run option 4, Non-destructive surface analysis, to
check the disk surface.
