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 missing bad track, 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 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.
