How to: Secure Erase your Solid State Drive (SSD) with Parted Magic

Erasing all the data on the SSD:
It is not safe to use DBAN Nuke or similar on SSDs. First, it's not good for the drive, and second, it wouldn't work properly anyway. Not good for the drive because it writes to the drive too many times. Wouldn't work properly because just like the OS, DBAN and similar cannot control where it writes to on the drive. The SSD's controller is responsible for that, and due to wear leveling algorithms, wouldn't get you the intended results. With an SSD, all you need is to perform a "secure erase."

Secure Erase:
Secure erase is where the SSD controller issues the ATA Securiy Erase Unit command that applies a voltage spike at a specific voltage to all of the NAND simultaneously flushing the stored electrons from the flash memory cells, thus cleaning the NAND. This in turn resets all the NAND cells on the SSD and leaves the drive's data in an unrecoverable state and at factory speeds.

Secure Erase Q and A: (link)

To Secure Erase Your SSD you will need:
  • To backup any information on the drive you are secure erasing if you want the data back after: (link)
  • Download parted magic and make a bootable CD or USB: Parted Magic

Video Tut:

Textual Guide: Warning: Spoiler! (Click to show)
  1. Download parted magic and make a bootable CD or USB: Parted Magic
  2. Once bootable load it and select option 1 (default settings)
  3. Once booted, at the main screen got to Start > System Tools > Erase Disk
  4. Now select the "Internal:Secure Erase command writes zeroes to entire data area" option which will write zeroes to your entire data area" option
  5. Select the disk that you want to secure erase
  6. If you get a message stating that your SSD drive is "frozen," click the Sleep button to put your PC to sleep, then wake up your system and start over from Step 3. If you don't get this message, move on to Step 7.
  7. Some drives indicate that they have a password requirement. Leave the password as "NULL" and click OK.
  8. Now a verify window will pop up, select "Yes" to continue.
    Note: If it prompts you to use the "enhanced" or "advanced" method do not use it, click no, it can write random data, and there is also the possibility that it may access parts of the drive that it shouldn't! It is basically an experimental, non-regulated setting that is meant to be "more secure."
  9. This shouldn't take long on your SSD, most likely only a few seconds. Now you are done.

Freeze Locked:
Basically "Freeze Locking" your SSD will not let it be allowed to be Secure Erased. If the UEFI/BIOS recognizes the SSD as plugged in at boot up then it will lock it. If you plug in the SSD after the computer is on then it will not be locked and it should be able to be Secure Erased normally.

  1. If your SSD is being "Freeze Locked" or not showing up then try this:
    You will get an option to put the PC to sleep, try that first then try to Secure Erase again
  2. If that still does not work:
    When you put the PC into sleep mode make sure you have any USB devices unplugged from the system and the Parted Magic USB/Live CD as well.
  3. If that doesn't work try below on top of the other suggestions:
    1. Reboot
    2. Enable AHCI mode in the UEFI/BIOS and "hot swap" on the SATA ports
    3. Save & exit
    4. Turn off the computer
    5. Unplug EVERYTHING on your SATA ports except for your CD/DVD drive
    6. Turn on and boot to Parted Magic
    7. When in the main GUI plug your SSD into a normal SATA 2 port

Thanks Sean! I keep forgetting where the stickies are due to the new layout (still like the old one better).

Time to wipe then sell everything in my desktop for college money!
