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 or solid-state 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 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 or 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 hard disk drive or solid-state drive, Lenovo provides the Secure Data Disposal
tool. To download the program, go to:
http://www.lenovo.com/support
Note: Running either program 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 a program provided by Lenovo. This program 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 program, 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 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 information system of
your antivirus software.
