• Use the recovery program provided by Lenovo to bring the storage devices 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 hard disk drives, solid-state drives, or hybrid drives for unexpected purposes.
To prevent leakage of data, it is important that you delete all the data from the storage devices when
you dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the
storage devices 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 Drive Erase Utility for Resetting the
Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the storage devices,
Lenovo provides the Secure Data Disposal
™ tool. Go to http://www.lenovo.com/support to download
these tools.
If an Encryption hybrid drive, 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 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.
