volume. By specifying write permissions, you can limit who is allowed to perform shredding operations.

more rows in the Format List, including the Last Data row.
If you selected Random in the Write Data field, repeat Step 5 until there are three or more rows
in the Format List, including the Last Data row.
CAUTION:
Although you can execute Shredding operations when there are less than three rows in the
Format List, you might not be able to completely delete data from the volume. Therefore,
HP recommends you define three or more rows in the Format List.
