Data Pattern
• Default (00-FF-00): Deletes the data in a volume by overwriting the volume three
times with dummy data. When the volume is overwritten for the first and the third
times, the volume shredding uses "00" (hexadecimal number) for the dummy data.
When the volume is overwritten for the second time, the volume shredding uses
"FF" (hexadecimal number) for the dummy data.
• User: Enables you to define the dummy data and how many times you want to
overwrite the volume.
Volume shredding selects 4-digit hexadecimal numbers at random for the dummy
data.
Random Data
You can enter hexadecimal numbers to be used as the dummy data. You can enter
hexadecimal numbers from 0 to FFFF.
