Enter the appropriate information for each defect.

4. When you are finished, the following message appears (nnn represents the information you just entered):

You have specified cylinder nnn, head nnn, byte offset nnn. Is this correct?

- Enter Y if the information is correct.

- Enter N if the information is incorrect. Repeat step 3.

5. To enter additional defects, repeat steps 3 and 4.

6. When you have finished entering all bad blocks, press ENTER at the prompt for a cylinder number. The following message appears:
