O&O SafeErase is a security and privacy application that provides users with the ability to permanently delete files, folders, and disk drives from their computers. It works by overwriting the data with random numbers, making the data unrecoverable. O&O SafeErase also lets users securely erase internet history, cookies, and other traces of online activity. It also has a “shredder” feature that allows users to securely delete files that have already been deleted, in order to make sure they are unrecoverable. Additionally, O&O SafeErase has the ability to securely delete files on external drives, such as USB sticks and external hard drives.
The discontinued DBAN was last updated in June 2015 and does not support SSD (SATA secure erase). The official website is now pushing users to use Blancco Drive Eraser, a commercial disk wiping tool.
