Subject: [dm-crypt] Random fill
Date: Sat, 29 Aug 2009 15:58:58 -0400	[thread overview]
Message-ID: <200908291558.58894.dmcryptmailman@strokerville.com> (raw)

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?

Thanks,
Stroker
