Another approach that I've seen flying around is to generate random string and use it's hashes for dd. There are some one-liners out there which do that with openssl, just one example: openssl enc -aes-256-ctr -pass pass:"$(dd if=/dev/urandom bs=128 count=1 2>/dev/null | base64)" -nosalt < /dev/zero > randomfile.bin Hope this helps. -- Best regards, Oleg Gelbukh /Alan > > > > *From:* Oleg Gelbukh [mailto:ogelb...@mirantis.com] > *Sent:* January-15-14 10:30 AM > *To:* OpenStack Development Mailing List (not for usage questions) > *Subject:* Re: [openstack-dev] [ironic] Disk Eraser > > > > > > On Wed, Jan 15, 2014 at 6:42 PM, Alexei Kornienko < > alexei.kornie...@gmail.com> wrote: > > If you are working on linux system following can help you: > > dd if=/dev/urandom of=/dev/sda bs=4k > > > > I would not recommend that as /dev/urandom is real slow (10-15 MB/s). > > > > -- > > Best regards, > > Oleg Gelbukh > > > > > :) > Best Regards, > > > > On 01/15/2014 04:31 PM, Alan Kavanagh wrote: > > Hi fellow OpenStackers > > > > Does anyone have any recommendations on open source tools for disk > erasure/data destruction software.
