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 click Empty recycle bin. • Use the Delete option. • Format your hard disk drive, using the software for initializing it. • Using the recovery program, provided by Lenovo, bring the hard disk drive back to the factory default settings. 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 people of bad faith might read and misuse the critical data on hard disk drives for unexpected purposes. To prevent leakage of data, it becomes very important that you take responsibility for deleting all the data from the hard disk drive when you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the hard disk 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 hard disk drive, Lenovo provides the Secure Data Disposal™ tool. To download the tool, go to: http://www.lenovo.com/support Note: Running the application will take a couple of hours. If an Encryption solid-state drive or a Disk Encryption hard disk drive 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 decrypted without the old key. This feature is enabled by ThinkPad Setup Menu Extension Utility and is available as a menu item in ThinkPad Setup. Using firewalls If your system is preinstalled with a firewall program, it protects against computer Internet security threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy. For more information about how to use the firewall program, refer to the help information system that comes with the program. Protecting data against viruses Your computer is preinstalled with an antivirus program so you can detect and eliminate viruses. The antivirus program is designed to help you detect and eliminate viruses. Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After 30 days, you must renew the license to continue receiving the antivirus software updates. For more information about how to use your antivirus software, refer to the help system of your antivirus software. Chapter 4. Security 47
