Any data remaining on the disk from before the format should be encrypted, and without the key, irrecoverable.ģ. Formatting the disk will remove the Bitlocker encryption. After the disk is encrypted, you can format the disk from "This PC" or Disk Management.Ģ. Depending on how the drive is configured, proceed to 3A or 3B to finish wiping the drive. When asked, choose to encrypt the entire device. Do not re-use encryption passwords for multiple devices or keep an association between a password and a drive if encryption is being used for secure wiping. Preferably, encrypt the device using a password. Use a long, randomly generated password and discard it after encrypting the drive. For the SSD media that needs to be securely erased, choose "Turn on BitLocker" and follow the prompts. Open the Control Panel, navigate to "System and Security," and choose "Manage Bitlocker" (or search for Bitlocker on the Start Menu)Ģ. You can perform this on a live system if you are decomissioning it, or your can perform this on an external/secondary drive that is connected to a Windows 10 machine.ġ. Securely Erasing an SSD with Bitlocker on Windows Today, most OSes provide built in encryption tools that can assist in securing an SSD. By formatting the drive and removing the encryption key, the SSD can be securely disposed of without the risk of data remaining on the drive. Using Encryption to Erase an SSDīy using whole disk encryption on an SSD, all of the data on the drive will become unreadable without the decryption key. Because of these two issues, SSDs must be wiped in a different manner. Wiping a disk using tools like DBAN will not write to these sections, leading to data remanence. SSDs also perform tasks called "wear leveling" which will remove certain sections of the disk from use, but these decomissioned sections may still retain data. Flash media is unaffected by magnets and cannot be wiped in this way. Traditional storage media like mechanical hard drives or tape based storage have storage physically writen to magnetic media, and therefore can be erased using tools like degaussers, which use powerful magnets to wipe the disks. Solid State Drives (SSDs), and other flash-based media like portable USB drives, store data as electric charges. Why can't normal methods be used to erase an SSD? ![]()
