Problem: Asus EE (no CD drive) in disuse with forgotten password and personal information

Question: How can I remove the content for sure?

2
  • Are you asking to backup (retrieve) the content or are you asking to wipe/erase it for resale?

Use the "Linux System Rescue CD" and type/run: DBAN (secure deletion) to erase/destroy data from the hard disk. This runs on a USB-stick too: http://www.sysresccd.org/Sysresccd-manual-en_How_to_install_SystemRescueCd_on_an_USB-stick

    I use DBAN, which is also on the SRD

  • Yeah, I think that's what I've ran before... just couldn't remember the name.

  • @RascalKing: I have heard about it. Are they the same? If not, which one is better?

  • Yeah, they are the same, boot to the SRd, type DBAN (which stands for Darik's Boot and Nuke), and then run through the options. It will give you a full DOD level wipe.

Boot Linux from an USB, doesn't really matter what flavor and run:

dd if=/dev/urandom of=/dev/sda

If you have two drives or have different drive names, switch 'sda' out for you destination drive. This will write random characters to your entire drive making recovery almost impossible.

Another option is DBAN (as David also mentioned, kudos) or "Darik's Boot and Nuke" is a open source program, that can be used from a USB drive to write random data over your old data (just like the example above).

Boot off a USB flash drive with Ubuntu, run gparted to wipe the main drive. I always keep a flash drive with bootable Ubuntu around; they're useful.

  • GParted will repartition the drive, not wipe the drive. If you just run GParted on a drive it can very easily be mounted and read with the right software regardless of the filesystem changes. I've had to do this.

# shred -vfz -n 25 /dev/hda

This command is available in most modern Linux distributions. It fills your disk with zeros 10 times. Information on the disk can be partially recovered only using very expensive techniques, that buyer of the old netbook, I think, doesn't posses.

  • I believe for SSDs, which often can be found in ASUS eeePCs, it's enough to write zeros only once, because SSDs store information without using rotating magnetic platters, as opposed to HDDs

You could try using Billix; this is a "super" USB distribution agreggate which provides LiveCD versions of Ubuntu, CentOS, Fedora, and DBAN as well.
