Epson Apex 20020 - Manual (Page 209)

Some of the messages change if the table is full or empty.
However, the way that you add a bad track or make a
correction is the same.
To add a bad track, follow these steps:
1. Press A. You see this prompt:
Enter cylinder number (1 - xxxx):
2. Type the number of the cylinder containing the bad track
you want to enter, and press Enter. You see this prompt:
Enter head number (0 - yy):
3. Type the head number for the bad track, and press Enter.
The maximum valid cylinder and head numbers (
XXXX
and
yy) vary according to the capacity of the hard disk.
To cancel the 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 appears 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.
Once you complete 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.
