You are right. Wiping a whole drive is a long process that's one of the reasons why I started using LUKS containers. Although before setting up Luks I use the urandom as well but it comes to the fore when the drive dies with the platters intact. At least I can rest assured knowing that the data cannot be retrieved easily. -- Kind regards, Yudi
