Oh, if it's SSD drives, don't do it this way, this is solely for plattered drives. If you are using an SSD, then you just need to issue a secure command to the drive and tell it to wipe itself--which you can do through hdparm: $~ hdparm --user-master u --security-set-pass PasSWorD /dev/sda #sets up security on the drive $~ hdparm --user-master u --security-erase PasSWorD /dev/sda # the point of no return delete everything on your SSD drive command On Sun, Dec 14, 2014 at 11:00 AM, Todd Millecam wrote: > > There's a lot of ways to do it, but they all do the same thing. > In bash: > $~ shred -zn10 /dev/sda > > That'll securely erase everything on block device /dev/sda--give it a > while to run as it's writing random numbers across the entire drive and > then finishing by writing nothing but 0s on it.
