Notice on deleting data from your solid state drive As computers spread into every corner of life, they process more and more information. The data on your computer, some of which is sensitive, is stored on the solid state drive. Before you dispose of, sell, or hand over your computer, be sure to delete data stored on it. Handing your computer over to someone else without deleting the loaded software, such as operating systems and application software, might even violate license agreements. You are advised to check the terms and conditions of those license agreements. There are methods that seem to delete the data: • Move the data to the recycle bin, and then empty the recycle bin. • Use the Delete option. • Format your solid state drive, using the software for initializing it. • Set the solid state drive back to the factory default settings using the recovery program provided by Lenovo. These operations, however, only change the file allocation of the data; they do not delete the data itself. In other words, the data retrieval processing is disabled under an operating system such as Windows. The data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of special software for data recovery. There is a risk that this data can be retrieved and used for unexpected purposes. To prevent leakage of data, it becomes very important that you take responsibility for deleting all the data from the solid state drive when you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the solid state drive with a hammer, or magnetically by means of strong magnetic power, thus making the data unreadable. But we recommend that you make use of the software (payware) or service (pay service) specifically developed for the purpose. For disposing of data on the solid state drive, Lenovo provides the Secure Data Disposal tool. To download the tool, go to: http://www.lenovo.com/support . Note: Running either application will take a couple of hours. If a solid state drive equipped with encryption features is supported and installed in your computer, you can logically dispose of all the data on the drive in a very short time by erasing the cryptographic key. The data encrypted with the old key is not physically erased but remains on the drive; however, it cannot be Chapter 4. Security 55
