Hello Aron and others, Your information is about wiping like there was no encryption, what takes much time. In many cases I use encryption so I don't have to wipe the disks when they are old! But I don't know so much about ecryptfs, normally I use dmcrypt/LUKS, where I can overwrite the volume header.
