So, I estimate it will take 80 hours to fill my drives via: dd if=/dev/urandom of=/dev/sdb1 There seems to be mixed opinions regarding the use of frandom or erandom. My question is, wouldn't the following command fill my drives with randommess? Much more quickly than urandom? dd if=/dev/zero of=/dev/mapper/encrypted_sdb1 Perhaps change the key afterward, or even delete/rebuild the dm-crypt block?
