Notice on deleting data from your storage drive

Some of the data stored on the storage drive might be sensitive. Handing your computer over to someone
else without deleting the loaded software, such as operating systems and application software, might even
violate license agreements. Be sure to delete data stored on the storage drive before you dispose of, sell,
or hand over your computer.
You can use the following methods to delete data from the storage drive:
• Move the data to the Recycle Bin, and then empty the Recycle Bin.
• Delete the data.
• Format your storage drive, using the software for initializing it.
• Use the recovery program provided by Lenovo to bring the storage drive back to the factory default
settings.
These operations, however, only change the file location 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 storage drives for unexpected purposes.
To prevent leakage of data, it is important that you delete 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 it is recommended that you use the software (payware) or service (pay service) developed for that
purpose. The process might take several hours.
For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the hard disk drive, Lenovo
provides the Secure Data Disposal™ tool. Go to http://www.lenovo.com/support to download the tool.
If a Disk Encryption hard disk drive or Encryption solid-state drive is supported and installed in your
computer, you can logically dispose of all the data on the drive in a 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 also available with the Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool.

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.
