Hard drives

Dan's computer was damaged and Acer is going to replace it, but he's worried about the data on it. How can he wipe the data? Leo says that there's a program called DBAN - Darik's Boot and Nuke that can wipe the drive pretty thoroughly. But Dan should understand that an SSD doesn't format the way a spinning hard drive does, and there can and will be some data leak, where someone could grab the data if they're really motivated. If he had encrypted the hard drive first, that data would be encrypted and they'd have to have the password to unencrypt it. So Leo always advises encrypting an SSD before using it.
