Using And Understanding Firewalls; Protecting Data Against Viruses - Lenovo ThinkPad Edge E120 User Manual

To prevent leakage of data, it becomes very important that you take responsibility for deleting all the data
from the hard disk drive or solid state 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 the Lenovo Web site at http://www.lenovo.com/support.
Note: Running the application will take a couple of hours.
If you use software designed for use with the hard disk drive to delete data stored on the solid state drive, it
will erase only data that is accessible by normal operation. It may not erase the hidden area of the flash
chip. Therefore, sometimes it may still be possible to read the data by use of special equipment or a special
tool. To prevent leakage of data from the solid state drive, it is recommended that you delete all data
on the flash chips by use of an application provided by Lenovo. This application called the ThinkPad
Setup Menu Extension Utility makes it possible to erase all the data on the flash chips of the solid state
drive from the ThinkPad Setup within a minute. To download this application, go to the Lenovo Web site
http://www.lenovo.com/support.
If Encryption solid state drive or Disk Encryption hard disk drive is supported and installed in your computer,
you can logically dispose of all the data on a device 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 disk; however, it cannot be
decrypted without the old key. This feature is enabled by the ThinkPad Setup Menu Extension Utility and is
available as a menu item in the ThinkPad Setup.

Using and understanding firewalls

unauthorized access, intrusions, and Internet attacks. It also protects your privacy.

the program.

Protecting data against viruses
