What are the different SafeErase methods, and which one should I use?
All of the O&O SafeErase methods provide a means of secure data deletion. Each overwrite data several times, making it impossible for unauthorized persons to get their hands on private or internal company data. As described above, there are both software and hardware methods of data recovery. Software methods fail where data has been completely and deliberately overwritten. The different methods follow official recommendations of institutions as the US National Security Agency (NSA). However, hardware methods are extremely advanced and can even gain data from hard disks that have been seriously physically damaged (e.g. after bomb blasts). The level you choose is dependent on your assessment of the importance of the data and the time you have available. The higher security the method, the longer the process will take. The lowest security level overwrites your data once with random data. What we’ve called “low security” overwrites your data with a pre-defined value three times, then with
