![]() 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 SSDÄ«y 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?
