Lenovo S9E, S10E manual Energy Star model information, 153

To prevent leakage of data, it becomes very important that you take responsibility for deleting all the data from the HDD or SSD when you dispose of, sell, or hand over your computer. You can destroy the data physically bysmashing the HDD with a hammer, or magnetically by means of strongmagnetic 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.

If you use software designed for use with the HDD to delete data stored on the SSD, 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 SSD, it is recommended that you delete all data on the flash chips by use of an application provided by Lenovo.
