This is especially important when it comes to deleting files securely. To prevent this from happening, the hard drive can be overwritten several times using special programs such as Darik’s Boot and Nuke – a method also recommended by the BSI.Īs already described in various articles, SSDs work completely differently than classic magnetic hard drives.
