Hard disk security
To protect passwords from unauthorized security attacks, several of the latest technologies and algorithms
are integrated into UEFI BIOS and hardware design of ThinkPad notebook computers.
To maximize security, do the following:
1. Set a power-on password as well as a hard disk password for your internal hard disk drive. Refer to
the procedures in "Power-on password" on page 50 and "Hard disk passwords" on page 50. For
security, a longer password is recommended.
2. If a Disk Encryption hard disk drive is installed in your computer, be sure to protect the contents of your
computer memory from unauthorized access by use of drive encryption software.
3. Before you dispose of, sell, or hand over your computer, be sure to delete data stored on it. Refer to
"Notice on deleting data from your hard disk drive" on page 54.
Note: The hard disk drive built into your computer can be protected by UEFI BIOS.
Disk Encryption hard disk drive
Some models contain the Disk Encryption hard disk drive. This feature helps to protect your computer
against security attacks on media, NAND flash or device controllers by use of a hardware encryption chip. For
the efficient use of the encryption feature, be sure to set a hard disk password for the internal storage device.
Notice on deleting data from your hard disk drive
As computers spread into every corner of life, they process more and more information. The data on your
computer, some of which might be sensitive, is stored on a hard disk drive. Before you dispose of, sell, or
hand over your computer, be sure to delete data stored on it.
Handing your computer over to someone else without deleting the loaded software, such as operating
systems and program software, might even violate license agreements. You are advised to check the
terms and conditions of those license agreements.
There are methods that seem to delete the data:
• Move the data to the recycle bin, and then click Empty recycle bin.
• Use the Delete option.
• Format your hard disk drive, using the software for initializing it.
• Using the recovery program to bring the hard disk drive back to the factory default settings.
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
