Preparation is Key
Before you start wiping your SSD, it’s essential to take a few precautions to ensure a smooth process.
Backup Your Data
If you haven’t already done so, make sure to backup any important data on your SSD. Wiping your SSD will erase all data, so it’s crucial to have a backup of your files, documents, and other important information.
Download Parted Magic
Head over to the Parted Magic website and download the latest ISO file. You can choose from a range of download options, including a direct download or a torrent file.
Create a Bootable USB Drive
Once you’ve downloaded the ISO file, create a bootable USB drive using a tool like Rufus or Etcher. This will allow you to boot into Parted Magic from your USB drive.
Booting into Parted Magic
Insert your bootable USB drive into your computer and restart your system. Enter the BIOS settings (usually by pressing F2, F12, or Del) and set the USB drive as the first boot device. Save your changes and exit the BIOS settings.
Your system should now boot into Parted Magic. You’ll be greeted with a simple menu that includes options to run Parted Magic, run MemTest86+, or exit the program.
Select Your Language and Keyboard Layout
Select your language and keyboard layout from the menu, and you’ll be presented with the Parted Magic desktop.
Wiping Your SSD with Parted Magic
Now it’s time to wipe your SSD using Parted Magic.
Identify Your SSD
Open the Parted Magic terminal and type the following command to list all connected disks:
sudo parted -l
This will display a list of disks, including your SSD. Make a note of the device name, which will be something like /dev/sda or /dev/nvme0n1.
Wipe the SSD
To wipe the SSD, use the following command:
sudo dd if=/dev/zero of=/dev/<device_name> bs=1M
Replace <device_name> with the actual device name of your SSD. This command will overwrite the entire SSD with zeros, effectively wiping all data.
Warning: This process is irreversible, so make sure you’ve backed up any important data and are certain you want to wipe the SSD.
Verifying the Wipe
To ensure that the SSD has been successfully wiped, you can verify the process using the following command:
sudo dd if=/dev/<device_name> bs=1M | md5sum
This will generate an MD5 checksum of the SSD’s contents. If the SSD has been properly wiped, the checksum should be a string of zeros.

What is Parted Magic and why is it used for securely erasing SSDs?
Parted Magic is a free, open-source, and bootstrap-based Linux distribution that provides a comprehensive set of tools for managing and securing storage devices. It is specifically designed to securely erase solid-state drives (SSDs) by overwriting data with zeros, thereby making it impossible to recover deleted files.
Parted Magic is an ideal choice for securely erasing SSDs because it can boot from a USB drive, allowing users to erase the main drive without worrying about overwriting the operating system or data. Additionally, Parted Magic is lightweight, easy to use, and supports a wide range of file systems and storage devices, making it a versatile tool for various erasing tasks.
What is the difference between quick and secure erase methods?
The quick erase method, also known as a rapid sanitize or cryptographic erase, is a fast process that deletes the encryption key on the SSD, making the data inaccessible. This method is quick but not secure, as it doesn’t physically overwrite the data on the drive.
In contrast, the secure erase method, also known as a full sanitize or physical erase, overwrites the entire drive with zeros, ensuring that all data is completely removed. This method is more time-consuming but provides a higher level of security. Parted Magic uses the secure erase method to ensure that all data on the SSD is completely erased and unrecoverable.
Can I use Parted Magic to erase other types of storage devices besides SSDs?
While Parted Magic is specifically designed for securely erasing SSDs, it can also be used to erase other types of storage devices, including hard disk drives (HDDs), USB drives, and memory cards.
