Oh.<br><br>On modern hardware, you don't actually need shred for a secure delete. <br><br><a href="http://www.anti-forensics.com/disk-wiping-one-pass-is-enough">http://www.anti-forensics.com/disk-wiping-one-pass-is-enough</a><br>

I should have mentioned in my first post that I have used DBAN in the past, but now I'm looking for other suggestions since it hasn't been recognizing the controllers in any of the servers I've had to wipe now.<br>

As mentioned I've been experimenting with shred. I've been booted to the CentOS-6.0-x86_64-minimal.iso and selected the option for Rescue. I don't enable networking or scan for the existing file system just jump into the shell. Run a fdisk -l to see what disks are configured, /dev/sda for example, then run shred -vfz -n 3 /dev/sda. This seems to do the same as the dd if=/dev/urandom of=/dev/sda bs=1G command but will run three iterations, well four actually since the -z option does a final overwrite with zeros at the end.<br>
