Lower number of times we overwrite volume header during the encryption of a partition if the user choose to wipe the driver. Latest studies show that even one pass is enough to make data irretrievable. A value of 3 is a conservative approach that enhance performance without scarifying security. http://www.infosecisland.com/blogview/16130-The-Urban-Legend-of-Multipass-Hard-Disk-Overwrite.html http://digital-forensics.sans.org/blog/2009/01/15/overwriting-hard-drive-data/
