Note: Running either 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.
